The course provides an introduction to the definition and classification of general stochastic processes. For Markov chains, we discuss the definition, transition probability matrices, classification of states, limiting properties. We broadly discuss two types of Markov chains with discrete state space, namely, Poisson process, and birth and death processes. We then discuss a gentle introduction to the Renewal Process. Here we discuss renewal equation, mean renewal time, and stopping time. Finally, we also discuss Markov Process with Continuous State Space, where we introduce the Brownian motion.

Objectives
The course begins with a gentle introduction to the exponential family of distributions. Several desired properties of the estimators like sufficiency, completeness, unbiasedness, etc. are subsequently discussed and related theoretical results are also demonstrated through examples. Further, different approaches for parameter estimation like the method of moments, maximum likelihood estimation, minimum mean square estimation, etc. are discussed. Subsequently, some basic concepts regarding statistical hypotheses testing are discussed. Here we cover ideas like simple and composite hypothesis, critical regions, TypeI and TypeII errors, and size and power of a test. Some optimal statistical hypothesis testing procedures like the most powerful test, uniformly most powerful test, unbiased test, monotone likelihood ratio test, etc. are discussed. Further, as a special case, the hypothesis tests are discussed for the exponential family case, where we discuss both the singleparameter and multiparameter settings.

Course Description
A positive integer is called a congruent number if it is the area of a rational right angled triangle. Fibonacci showed that 5,6,7 are congruent numbers and Fermat proved that 1 is not a congruent number. Indeed, the problem of classifying congruent numbers can be traced back to at least 10th century and is still unresolved. In particular, the following conjecture is open: Given a positive integer n, is there a (finite step) algorithm to determine if n is a congruent number or not? Modern developments relate the congruent number problem to the arithmetic of elliptic curves and modular forms. In this course, we will study the basic theory of elliptic curves, modular forms and their relation with the congruent number problem. Note that the theory of elliptic curves have significant applications in cryptography.

Aims of the course
Model theory can be roughly described as “logic + algebra” and it studies classes of mathematical structures from the logical perspective. Many branches of mathematics are titled ‘ theory’ where  is a placeholder for group, field, order etc. where a theory is a set of axioms/sentences written in a formal language, and a ‘model’ of such a theory is a structure that satisfies all the axioms. The course aims to cover some general abstract techniques and then focus on some interesting theories/results across different parts of mathematics including algebra, lattices and algebraic geometry.
Syllabus
 The place of model theory in pure mathematics.
 Structures and homomorphisms: syntax, structures, homomorphism, isomorphism, substructure, embedding, examples.
 Semantics: evaluation of terms, satisfaction of formulas, elementary embedding, theory, elementary equivalence, examples.
 Compactness: Ultrafilters, product structures, ultraproducts, compactness theorem, applications, LowenheimSkolem theorem.
 Theories: dense linear orders (DLO), algebraically closed fields (ACF),real closed fields (RCF).
 Categoricity: definition, Vaught’s test, backandforth method, RyllNardzewskitheorem, Morely’s categoricity theorem.
 Quantifier elimination: explanation and characterization, Chevalley’s theorem, TarskiSeidenberg theorem.

Aims of the course
The concept of a Grothendieck topos was introduced in the pioneering work of A. Grothendieck in algebraic geometry to provide a vast generalization of the concept of a sheaf on a topological space. The course will introduce students to the definition and properties of sheaves, not only on topological spaces but also on sites. A Grothendieck topos is a category of sheaves on a site, and possesses very rich categorytheoretic structure. Although the course will mostly deal with sheaves of sets, sheaves of abelian groups and rings etc. will also be introduced on the way. The language of category theory necessary for the course will be introduced at the start.
Syllabus
 Categorical preliminaries: category, morphisms, functor, natural transformation, universal constructions, adjoint functors, limits and colimits, exponentials.
 Functor categories: limits and colimits, subobject classifiers.
 Lattices and algebras: lattices, distributive lattices, implication, negation,Boolean algebra, Heyting algebra, subobject lattices in functor categories.
 Logic: interpretation of logical connectives in functor categories, quantifiers as adjoints.
 Sheaves on topological spaces: definition of sheaves, subsheaves, sieves,germ, stalk, bundles, crosssection, sheaves with algebraic structure, inverse image sheaves.
 Grothendieck topologies: generalized neighbourhood, sites, the Zariskisite, sheaves on a site, Grothendieck topos, associated sheaf functor.
 Properties of Grothendieck toposes: limits, colimits, exponentials, subobject classifier.

Course Description
Analytic number theory is a major branch of number theory. One of the basic theme of analytic number theory is that the study of distribution of prime numbers is deeply related with some complex analytic properties of certain Dirichlet series. The main goal of this introductory course is to study two fundamental theorems under this theme (i) Dirichlet Theorem on Primes in Arithmetic Progression: This theorem discusses how the distribution of primes numbers in an A.P. is related to the nonvanishing of certain Dirichlet Lfunction. (ii) The Prime Number Theorem: This theorem relates the natural density of primes with the behaviour of the Riemann Zeta function on the line Re(s) =1 in the complex plane. We will also introduce modular forms and the associated Lfunctions. Modular forms are certain analytic functions defined on the upper half of the complex plane which have many symmetries with respect to the matrix group SL2(Z). Given a ’nice’ modular form one can naturally associate an Lfunction, which can also be expressed as a Dirichlet series on the complex plane. The Lfunction of a modular form is a central object of study in number theory both from analytic as well as arithmetic point of view.

Course description
During the last four decades, it has been realized that some significant problems in number theory can be solved using techniques from the theory of dynamical systems. This influential approach has lead us to one of the forefronts of modern mathematical research. Our course aims to convey the central concepts and basic techniques of the theory to the students and to develop their background to pursue further. The course will be self contained. We shall begin from scratch and work out the details.
Course contents
Broadly the following topics are covered in details with varieties of examples and applications to metric umber theory:
Measure preserving transformation and its examples, Recurrence properties, Topological dynamics, Conditional expectations, Main ergodic theorems, Subadditive ergodic theorem, Ergodicity and its examples, Spectral approach to ergodicity, various applications of Birkhoff’s individual ergodic theorem, Mixing and its examples, Equidistribution, Unique ergodicity, Weyl’s theorem on equidistribution of polynomials, Ergodic measures are precisely the extreme points, Existence and uniqueness of conditional probability measures, Ergodic decomposition.
If time permits, we may discuss several connections between Diophantine approximation and diagonal flows on the space of lattices and some recent developments.

Aims of the course
Combinartorics is an area of mathematics that, at elementary level, deals with problems in counting/enumeration, especially in the realm of finite sets. However the supply of problems as well as the methods to solve them come from a variety of domains of mathematics ranging from algebra, analysis, number theory, geometry, probability theory and so on. Leon Mirsky has rightly said: ”combinatorics is a range of linked studies which have something in common and yet diverge widely in their objectives, their methods, and the degree of coherence they have attained”.
This course will introduce techniques from three popular branches of combinatorics that are of areas of active research currently, namely extremal combinatorics, extremal graph theory and additive combinatorics over dyadic groups. The emphasis will be on the techniques than the solutions of the problems.
Syllabus
 Extremal combinatorics with set systems: Hall’s marriage theorem, Sperner’slemma, LubellYamamatoMeshalkin inequality, KruskalKatona theorem, ErdosKoRado theorems.
 Extremal graph theory: Mantel’s theorem, Turan’s theorem, Dirac’s theorem, ErdosStoneSimonovits theorem, Szemeredi’s regularity lemma, Triangle removal lemma, Roth’s theorem for 3 term arithmetic progressions.
 Additive combinatorics with dyadic groups: Discrete Fourier transform,Plancherel’s theorem, Bogolyubov’s lemma, Arithmetic regularity and removal lemmas, Coincidence of algebraic and statistical independence of Bernoulli r. v.s, Rudin’s inequality, Sets with small sumsets: Rusza’s covering lemma, Freiman’s theorem.

Course Description
This aim of this course is to get introduced to certain important topics in number theory; both from arithmetic and analytic side. The topics include Zeta functions and Lfunctions, modular forms, quadratic forms, study of polynomial equations over finite fields. These topics have application in various other traditional branches of mathematics and also in computer science and physics. On the arithmetic side, we will begin with the study of polynomial equations over finite fields and the law of quadratic residue. We will then move into the padic world. Theory of quadratic forms over rational numbers, padic numbers, finite fields and the interrelation between them will be studied. On the analytic side, we will introduce Riemann Zeta function and more generally Dirichlet Lfunctions. We will discuss the significance of analytic properties of these functions in theorem on primes in arithmetic progression and prime number theorem. We will briefly discuss some basic properties of modular forms (for SL_{2}(Z)). The relation between elliptic curves and modular forms will be outlined.

Objectives
The course will provide a theoretical foundation for constructing and studying Markov chain Monte Carlo (MCMC) algorithms, along with tools for analyzing MCMC output. Special focus will be given on rates of convergence of a Markov chain and comparing different MCMC algorithms. The course will primarily focus on discretetime Markov chains on general state spaces. The objective is to equip students with the tools to develop, study, and implement an MCMC algorithm for any given problem.
Syllabus
This course presents the theoretical and practical challenges of implementing a discretetime general state space Markov chain Monte Carlo algorithm. MetropolisHastings, Gibbs samplers, and other componentwise algorithms are discussed in detail. The theoretical part of the course focuses on studying rates of convergence of Markov chains, and establishing the existence of a Markov chain central limit theorem. The practical challenges of implementing these algorithms, such as stepsizes, stopping criterion, output analysis, and implementation in statistical software are also discussed in detail.

Aims of the course
The letter K in Ktheory stands for the German word “Klasse”, and the classification of various kinds of mathematical objects is the main goal of the subject by associating to them their classes in certain abelian groups. Algebraic Ktheory deals with projective modules over a ring whereas topological Ktheory studies vector bundles over a topological space. A common and more general setting is that of categories with some additional structure.
The course will begin with the study of the Grothendieck group, K_{0}, associated with rings, topological spaces, symmetric monoidal categories, and exact categories. Through Bass’ K_{1 }and K_{2 }constructions we will motivate higher Ktheory. Quillen’s genius constructions of higher Kgroups and the study of various properties will constitute the final part of the course. This final part will be covered in detail if the students are familiar with the fundamental group construction.
Syllabus
 Projective modules, vector bundles, symmetric monoidal categories, exactcategories.
 The Grothendieck group and K_{0 }of rings.
 Topological Ktheory and Swan’s theorem.
 Bass’ K_{1 }and K_{2 }for rings.
 Geometric realization of a category.
