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...

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...

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 [...

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...

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...
