Title: Brownian Motion - Feynman's view

Abstract:Starting with the problem of heat equation witha potential and using Lie-Trotter product formula, Feynmanhas a heuristic way of explaining Brownian Motion.We shall discuss this. If time permits we shall discussWiener and Ito integrals.

Title: A Study on Fractal Interpolation in Shape Preserving and in Numerical Methods for Ordinary Differential Equations

Interpolation is an essential tool to approximate the unknown function from its samples. Many situations, when data arises from various complex phenomena, the data exhibits irregularity. Giving smooth approximation for these data may not be suitable. Fractal interpolation provides a non-smooth...

Title: Secant Bundles on Symmetric Power of Curves.

Abstract: Let $C$ be a smooth, projective, irreducible curve over the
field of complex numbers, and $C^n$ denotes the $n$-fold Cartesian
product of $C$. The symmetric group of $n$ elements acts on $C^n$ and
let $S^n(C)$ be the quotient. This is a smooth, irreducible, projective...

Speaker: Dr. Swarup Panda, IIISER Kolkata
Title: Inverses of graphs and reciprocal eigenvalue properties

Abstract
In Combinatorial Matrix Theory, the study of graph structures via dif- ferent properties of matrices associated with it is an interesting and popular topic. Among the various matrices associated with a graph, the adjacency matrix is probably the most popular and widely...

Date/Time: Friday, February 8, 2019 - 04:35 to 05:30
Venue: LH 5
Speaker: Professor Probal Chaudhury, ISI Kolkata
Title: Optimization by Monte Carlo

Abstract : I shall discuss how Monte Carlo methods can be used to solve complex optimization problems. In particular, I shall discuss the simulated annealing algorithm.

Venue: Seminar Hall
Speaker: Sauvik Mukherjee, Presidency University, Kolkata,
Title: POISSON STRUCTURES ON CLOSED MANIFOLDS

Abstrat: We prove an h-principle for poisson structures on closed manifolds. Equivalently
we prove h-principle for symplectic foliation (singular) on closed manifolds. On open
manifolds however the singularities could be avoided and it is a known result by Fernandes
and Frejlich [...

Venue: Seminar Hall
Speaker: Dr. Varun Thakre, International Centre for Theoretical Sciences (ICTS-TIFR), Bengaluru (India)
Title: Generalised Seiberg-Witten equations and de-generate metrics

Abstract: Gauge theories, which have their origin in physics, have had a profound effect on mathematics and nowhere is it more strikingly evident than in dimension four. Seiberg-Witten equations and Seiberg-Witten invariants have proven to be powerful instruments for the study of smooth...

Speaker: Dr. Pervez Sarwar , ISI Kolkata
Title: Algebraic K-theory and homology stability

Abstract: We shall begin with the homotopy invariance property of K-theory.After reviewing monoids and monoid algebras, we present some results which aremonoid version of the homotopy invariance property in K-theory. This answers a question ofGubeladze. Next, we will discuss the monoid version...
