Title: Around Property (T) for Quantum Groups
Kazhdan's property (T) is a notion of fundamental importance, with numerous applications in various fields of mathematics such as abstract harmonic analysis, ergodic theory and operator algebras. By using property (T), Connes was the first to exhibit a rigidity phenomenon of...

Title: A model for non-commutative vector lattices

We shall begin with a characterization of algebraic orthogonality in C^*-algebras in terms of order and norm. We apply this chacterization to propose a model of ``Absolutely ordered spaces'' which turns out to be a vector lattice under `commutative' conditions. This model suits to operator...

Title: Introduction to smooth manifolds

In this talk, we will introduce the concept of a smooth manifold and work out some examples. If time permits, we will define what is theTangent and Cotantent space of a manifold at a given point.

Title: Projective normality of line bundles of the type $K_X+\pi^*L$ on a ramified double covering $\pi:X\to S$ of an anticanonical rational surface $S$

Abstract:- Suppose $X$ is a minimal surface, which is a ramified double covering $\pi:X\to S$, of a rational surface $S$, with dim $|-K_S|\geq 1$. And suppose $L$ is a divisor on $S$, such that $L^2\geq 7$ and $L\cdot C\geq 3$ for any curve $C$ on $S$. Then the divisor $K_X+\pi^*L$ on $X$, is...

Title: Maximal surfaces, Born-Infeld solitons and Ramanujan's identities

Abstract: In the first part of the talk we discuss a different formulation for describing maximal surfaces in Lorentz-Minkowski space $ \mathbb{L}^3:=(\mathbb{R}^3, dx^2+dy^2-dz^2) $ using the identification of $ \mathbb{R}^3 $ with $ \mathbb{C}\times \mathbb{R} $. This description of maximal...

Title: Rankin-Cohen brackets and identities among eigenforms
Abstract :- Identities connecting modular forms (in particular, eigenforms) have attracted the attention of many mathematicians since they imply nice identities among their Fourier coefficients. It is quite natural to ask whether the property of being a Hecke eigenform is...

Venue: NISER

 This will be an introductory summer school on "J-Holomrphic Curves and Gromov-Witten Invariants".We hope to cover the foundations of this subject by following the book "J-Holomorphic Curves and Symplectic Topology" by Dusa McDuff and Dietmar Salamon. Quite a few young mathematicians from India...

Speaker: Dr. Soumyashant Nayak, University of Pennsylvania
Title: The Many Forms of the Pythagorean Theorem

The well-known Pythagorean theorem which relates the lengths of sides of a right triangle to the length of the hypotenuse dates as far back in time as the Babylonians. Later in school when one gets a flavour of trigonometry, this result is neatly packaged in the equation $cos^2 \theta + sin^2 \...
