Title: Geometry and Function Theory in Several Complex Variables

There is a deep interplay between geometry and holomorphic function theory on domains in $\mathbb{C}^n$, $n>1$, which is quite unlike the situation in $\mathbb{C}$. This leads to striking new phenomena in higher dimensions that are absent in the one dimensional setting. We will begin by...

Date/Time: Tuesday, February 21, 2017 - 15:00 to 16:00
Venue: Seminar Room, School of Mathematical Sciences
Speaker: Dr. Samik Basu, Ramakrishna Mission Vivekananda University
Title: Homotopy groups of highly connected manifolds

We shall discuss a new method of computing (integral) homotopy groups of certain manifolds in terms of the homotopy groups of spheres. The techniques used in this computation also yield formulae for homotopy groups of connected sums of sphere products and CW complexes of a similar type. In all...

Date/Time: Monday, February 20, 2017 - 11:30 to 12:30
Venue: Seminar Room, School of Mathematical Sciences
Speaker: Dr. Neeraja Sahasrabudhe, IIT, Bombay
Title: Interacting Urn Processes

Randomly evolving systems with components that interact with each other have been of great interest in research. In particular, in this talk, we will discuss interacting urn processes with reinforcement. We consider N interacting two-colour Friedman urns and discuss the synchronization limit and...

Venue: Conference Room, School of Mathematical Sciences
Speaker: Dr. Pradeep Kumar Rai, Bar-Ilan University, Israel
Title: Order of the Schur multiplier of finite p-groups

We shall derive some bounds on the order of the Schur multiplier of finite p-groups. We shall also classify finite p-groups having Schur multiplier of maximum order. Finally we shall discuss the Schur multiplier and covering groups of special p-groups having derived subgroup of maximum order....

Date/Time: Thursday, February 16, 2017 - 15:30 to 16:30
Venue: Seminar Hall, SMS
Speaker: Sujeet Kumar Singh, NISER
Title: Modular forms and Sturm bounds
Date/Time: Wednesday, February 15, 2017 - 19:00 to 20:00
Venue: Seminar Hall, Mathematics Department
Speaker: Ritwik Mukherjee, NISER
Title: Poincare Duality

We will explain what it means to integrate a top form on a manifold. We will then state the second version of Stokes Theorem. After that, we will give the statement of Poincare Duality for smooth manifolds.

Date/Time: Monday, February 13, 2017 - 19:00 to 20:00
Venue: Mathematics Department Seminar Hall
Speaker: Ritwik Mukherjee, NISER
Title: Integration on Manifolds

We will explain what it means to integrate differential forms on a manifold and state Stokes Theorem. We will see how it generalizes the fundamental theorem of calculus and Green's theorem.

Date/Time: Monday, February 13, 2017 - 11:30 to 12:30
Venue: Seminar Room, School of Mathematical Sciences
Speaker: Dr. Prosejit Roy, TIFR-CAM, Bangalore
Title: Extremal function for the singular Moser-Trudinger inequality
Date/Time: Friday, February 10, 2017 - 09:35 to 10:15
Venue: Mathematics Seminar Room
Speaker: Amit kumar, Research scholar, SMS, NISER
Title: Operator ideals

The concept of Operator Ideals will be explained through examples and several properties. These objects first occurred in the famous work The Memoirs'' of A. Grothendieck published in 1955. Since then, it has taken form of a vast theory of Operator Ideals.
