Title: Some results in the topology of real algebraic varieties

The topology of real algebraic varieties is the study of the topology of objects that can be defined real algebraically, particularly the restrictions that the real algebraic structure imposes on the topology. The main problem that motivated interest in this area is the so called Hilbert's...

Date/Time: Wednesday, January 18, 2017 - 18:30 to 20:00
Venue: Seminar Hall, Mathematics Department.
Speaker: Dr. Ritwik Mukherjee, School of Mathematical Sciences, NISER Bhubaneswar.
Title: Introduction to Smooth Manifolds

This is a planned series of informal lectures, where we develop the theory of smooth manifolds. We will start from scratch keeping prerequisites to a bare minimum.

Title: Pseudo-Differential Operators on Heisenberg Groups

The theory of pseudo-differential operators has provided a very powerful and flexible tool for treating certain problems in linear partial differential equations. The importance of the Heisenberg group in general harmonic analysis and problems involving partial differential operators on...

Venue: Mathematics Seminar Room
Speaker: Dheeraj Kulkarni, ISI KOlkata
Title: Racks and Knots

A rack is a set with a binary operation that satisfies properties similar to the conjugation operation in a group. Racks appeared in the context of knot theory as complete invariants. We will show how to extend the notion of racks for knots which satisfy a certain differential relation. These...

Speaker: Dr. Harendra Singh, IIT(BHU)
Title: WEAK ASYMPTOTIC AND ENTROPY WEAK ASYMPTOTIC SOLUTION FOR A NON-STRICTLY HYPERBOLIC SYSTEM OF CONSERVATION LAWS

A weak asymptotic solution developed by Panov and Shelkovich, is constructed for piecewise known solutions to a prolonged system of conservation laws by introducing δ, δ' , δ'' and δ''' waves along a discontinuity curve, which in turn implies the existence of weak asymptotic solutions for the...

Date/Time: Tuesday, November 15, 2016 - 13:30 to 14:30
Venue: Mathematics Seminar Hall
Speaker: Somnath Basu, IISER Kolkata

Abstract: We shall discuss associative binary structures and analyze why such a structure is not a homotopy invariant. This naturally leads to higher associative structures, often called $A_\infinity$ structures, which are prevalent in topology, geometry and mathematical physics. We shall...

Date/Time: Monday, November 7, 2016 - 11:35 to 12:30
Venue: Mathematics Seminar Hall
Speaker: Gopinath Panda, IIT, Bhubaneswar
Title: Optimal Balking Strategies in Markovian Queues with Vacations

Abstract: Queueing theory is vastly used to study service systems arising in management problems, where customers are considered to be indifferent in the sense that the decisions to control a system, are only made by the management and the users are impelled to follow the decisions. However, for...
