We will have  *Sridhar Narayanan* speaking on our RTAG seminar from 2pm to
3:30pm on Tuesday.
Here are the necessary details about his 3rd talk:

DDT: Tuesday, 16 August,  2:00 – 3:30 pm

Venue : Room No 215, Department of mathematics.
Title: Okounkov-Vershik approach to the representation theory of symmetric
groups.

Abstract: In this series of talks we will bootstrap the representation
theory of symmetric groups inductively, following the 2005 revision of
Vershik's and Okounkov's seminal paper on the topic.

We have now a dedicated website where one can find the notes and resources
from the past meets and announcements of the upcoming meetings:

Speaker: Jeff Adler, American University.

Title: P-adic groups: What and why?

Abstract:

After a review of Pontryagin duality, I will give an introduction to p-adic numbers, emphasizing their role in number theory, and will conclude with a description of part of the Langlands Program, which brings together number theory and harmonic analysis.

Commutative algebra seminar

===================

Speaker: Suprajo Das, IIT Bombay

Date: Thursday, 18 August, 3.30-5.00 pm

Title: Numerical aspects of the epsilon multiplicity-II

Abstract: In the second talk on this topic we will describe some instances where the length function associated with the epsilon multiplicity is a quasi-polynomial. We will mostly emphasize on the results of Herzog-Trung and Herzog-Puthenpurakal-Verma which together show that the epsilon multiplicity of a monomial ideal in a polynomial ring is a rational number. If time permits we will also discuss some extensions of these results.
