Title: Generalized Gini Index based on U-statistics

Gini index (G), a scaled version of Gini’s mean difference (GMD), is a U-statistic of degree two. In this presentation, I will present a general approach to construct a new class of inequality measures called ad-hoc inequality measures (AIM) which are based on U-statistics of degree higher than...

Title: Locally compact quantum groups: the von Neumann algebraic approach-4

Lecture series abstract: We will survey the von Neumann algebraic approach to locally compact quantum groups in the sense of Kustermans and Vaes, roughly following the treatment by Van Daele. We will begin with an intro to the theory of weights of von Neumann algebras. We will then proceed to...

Title: Control theory in partial differential equations

I shall discuss on control problems governed by the partial differential equations-mainly compressible Navier-Stokes equations,visco-elastic flows. I shall mention some of the basic tools applicable to study the control problems. We mainly use spectral characterization of the operator associated...

Title: Around Property (T) for Quantum Groups

Kazhdan's property (T) is a notion of fundamental importance, with numerous applications in various fields of mathematics such as abstract harmonic analysis, ergodic theory and operator algebras. By using property (T), Connes was the first to exhibit a rigidity phenomenon of...

Venue: Mathematics Seminar Room

Speaker: Anil Kumar Karn, NISER, SMS

Title: A model for non-commutative vector lattices

We shall begin with a characterization of algebraic orthogonality in C^*-algebras in terms of order and norm. We apply this chacterization to propose a model of ``Absolutely ordered spaces'' which turns out to be a vector lattice under `commutative' conditions. This model suits to operator...

Venue: Mathematics Seminar Room

Speaker: Anantadulal Paul, NISER

Title: Introduction to smooth manifolds

In this talk, we will introduce the concept of a smooth manifold and work out some examples. If time permits, we will define what is theTangent and Cotantent space of a manifold at a given point.
