Title: Gaussian structure of non-Gaussian distributions and contemporary theorems

Classical distribution theory in higher dimensions is largely focused on the Gaussian distribution. However, for the Gaussian distribution it is well known that every marginal distribution, every conditional distribution and all linear transformations are also Gaussian. Besides, it is also...

Speaker: Dr. Gautam Borisagar, Zakir Husain Delhi College
Title: Iwahori-Hekce model for supersingular representation for $GL_2(Q_p)$

We first recall the fundamental work of Barthel, Livne and Breuil on the mod p representation theory of GL2(Qp) and then present a variant of their approach in which a supersingular representation of GL2(Qp) is realized as a quotient of a representation induced from the Iwahori subgroup, instead...

Venue: LH-301
Speaker: Anindya Ghatak, NISER, Bhubaneswar
Title: Order theoretic properties in $C^*$ algebra and its generalisation
Abstract: In this talk, we shall discuss order theoretic properties in $C^*$-algebras and their generalisation. We begin with order unit spaces and base norm spaces and establish a duality relation.Then we generalize it to a more general setting of order smooth p-normed spaces...

Venue: LH-101
Speaker: Dr. Sudeshna Basu, George Washington University, USA
Title: Stability of ball properties in Banach spaces
Abstract: In this work, we study certain stability results for Ball Separation Porperties in Banach Spaces leading to a discussion in the context of operator spaces. In this work, we study certain stability results for Small Comibiantion of Slices Property (SCSP) leading to a...

Venue: PL-8
Speaker: Anoop V. P., NISER, Bhubaneswar
Title: Hardy - Littlewood Maximal Functions on Sphere

Abstract:  Hardy - Littlewood maximal function is one of the most fundamental operators in real analysis with many applications in different areas. In the seminar we will discuss about the Hardy- Littlewood function on sphere and its properties. Also the maximal function on sphere for weighted...

Date/Time: Wednesday, January 28, 2015 - 16:30 to 17:30
Venue: LH 101
Speaker: Professor A. Sankaranarayanan, TIFR, Mumbai
Title: Riemann zeta-function and it's influence on a problem of Srinivasa Ramanujan

Abstract : We discuss about the large values of the Riemann zeta-function on the line $1$ and it's consequence to the error term of the summatory function of $d^2(n)$ for $1 \le n \le x$ for large $x$ considered by Srinivasa Ramanujan where $d(n)$ denotes the sum of the positive divisors of the...

Date/Time: Tuesday, January 27, 2015 - 11:35 to 12:35
Venue: LH-301
Speaker: Moni Kumari, NISER, Bhubaneswar
Title: L-functions

Abstract: L-functions are generating functions formed out of local data associated with either an arithmetic object or with an automorphic form. These functions are special examples of so-called Dirichlet series. Some L-functions have interesting properties like analytic or...

Date/Time: Friday, January 16, 2015 - 15:30 to 16:30
Venue: LH-301
Speaker: Dr. Atish Sahu, Nagaland University SASRD, Medziphema
Title: Construction of Neighbor Balanced designs

Spatial heterogeneity in terms of trends or periodicity in blocks may affect the outcome of experiments, especially in agricultural experiments. The conventional randomized allocation of treatments to plots in a block may result in lesser precision. It has been commonly found that the...

Date/Time: Thursday, January 15, 2015 - 11:35 to 12:35
Venue: LH-101
Speaker: Gaurish Korpal, NISER, Bhubaneswar
Title: Celebrating 110th birthday of D. R. Kaprekar

Abstract: Dattarya Ramchandra Kaprekar was an Indian recreational mathematician who described several classes of natural numbers. The motive of this talk is to give a flavor of Elementary Number Theory and Iterations, by discussing the contributions of D. R. Kaprekar. I will...

Date/Time: Monday, January 12, 2015 - 11:35 to 12:35
Venue: LH 101
Speaker: Dr. Pritam Ghosh,
Title: Dynamics of outer automorphisms of free groups
Abstract: We will first look at some geometric properties of a free group and follow it up by introducing the Train track theory which is a vital tool for studying dynamics of outer automorphisms of free groups. Given a finite rank free group $F$ of rank $\geq 3$ and two...
