Title: Distribution of Primes

In this lectures, we would discuss probabilistic model of primes leading to heuristics about their distribution. We would see many surprising irregularities popping up alongside expected results. A survey of several recent and important results would be presented in a way accessible to non-...

Title: Regular characters of general linear groups over principal ideal local rings

Let F be a non-Archimedean local field with ring of integers O and finite residue field k of odd characteristic. In contrast to the well-understood representation theory of the finite groups of Lie type GL_n(k) or of the locally compact groups GL_n(F), representations of groups GL_n(O) are...

Speaker: Sudarshan Kumar, University of Concepcion, Chile
Title: On conservation laws with discontinuous flux

Conservation laws with discontinuous flux appears in the models of two phase flow in porous media, traffic flow with discontinuous road surface, clarifier thickener models of continuous sedimentation, enhanced oil recovery process etc. In this talk we begin with an introduction to both...

Venue: SMS seminar hall
Speaker: Pratyusha Chattopadhyay, Indian Statistical Institute - Bangalore
Title: Relation between orbit spaces of unimodular elements and its application

This is a topic in classical algebraic K-Theory. I will recall definitions of elementary linear group, elementary symplectic group, linear transvection group, symplectic transvection group and symplectic group w.r.t. any alternating form. These groups have natural action on the set of unimodular...

Title: ON THE FOURIER COEFFICIENTS OF A COHEN-EISENSTEIN SERIES

In the first part of this talk, we present a formula for the coefficients of a weight 3/2Cohen-Eisenstein series of squarefree level N. This formula generalizes a result of Gross and it provesin particular a conjecture of Quattrini. In the second part, we explain the proof of this formula andas...

Date/Time: Tuesday, August 23, 2016 - 10:30 to 11:30
Venue: Mathematics Seminar Room
Speaker: TSSRK Rao, ISI, Bangalore
Title: Almost isometric ideals in Banach spaces
In this talk we introduced the notion of an almost isometric ideal based on the Principle of Local reflexivity and study its properties.
The talk will also be accessible to students who had a first course in Functional Analysis.

Venue: SMS, Seminar Room
Title: Some spectral results on power graphs of finite cyclic and dihedral groups
Abstract: There are a number of graphs associated with semigroups and groups. The Cayley graph is the oldest and most popular among them whereas the concept of power graph is a recent development. The power graph $G(G)$ of a finite group $G$ is the graph whose vertices are the...
