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....

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:

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.

Date/Time:
Wednesday, February 8, 2017 - 19:00 to 20:00
Venue: Mathematics Department Seminar Hall
Speaker: Ritwik Mukherjee, NISER
Title: Introduction to Smooth Manifolds

We will explain what is a differential k-form and define the De Rham Cohomology of a smooth manifold.

Date/Time:
Tuesday, February 7, 2017 - 13:30 to 14:30
Venue: Mathematics Department Seminar Hall
Speaker: Ronnie Sebastian, IIT Bombay
Title: The Langlands Conjectures

The aim of this talk is to describe some conjectures which are part of the Langlands program.The talk is aimed at non-experts and should be accessible to a broad audience. 

Date/Time:
Monday, February 6, 2017 - 15:30 to 16:30
Venue: Seminar Room, Mathematics Department
Speaker: Deepika Kumari, Guru Gobind Singh Indraprastha University, Delhi
Title: Introduction to the Chen's biharmonic conjecture

In my presentation, I will give some brief introduction to biharmonic submanifold. Also, I will introduce the Chen's conjecture of biharmonic submanifold and present some recent developments of conjecture. 

Date/Time:
Thursday, February 2, 2017 - 18:30 to 20:00
Venue: Mathematics Department Seminar Hall
Speaker: Ritwik Mukherjee, NISER
Title: Introduction to Smooth Manifolds

We will continue with the discussion on (co)tangent bundle of a manifold. We will define the differential of a smooth map and state the implicit function theorem. We will also work out some concrete examples.
