Title: Theory of Regression Analysis with Applications

Regression analysis is a branch of statistics that provides us with tools to model a relationship between variables. In this presentation, we will discuss two types of regression models: the classical linear regression and non-parametric regression. Linear regression analysis aims to fit a...

Title: Reducing submodules of Hilbert modules with an invariant kernel

We show that $\mathcal H$, with an $\mathfrak S_n$ invariant reproducing kernel $K$on an $\mathfrak S_n$ domain in $\C^n$, splits into reducing submodules $\mathbb P_{\bl p} \m H$, over the invariant ring $\C[\boldsymbol z]^{\mathfrak S_n}$, indexed by the partitions $\bl p$ of $n$. We then...

Title: Mixed Multiplicities and Rees’ theorem for filtrations

In this talk I will discuss mixed multiplicities of (not necessarily Noetherian) filtrations of m-primary ideals in a Noetherian local ring (R, m). I will give the construction of a real polynomial whose coefficients give the mixed multiplicities generalizing the classical theory for m-primary...

Title: Poisson algebras associated to unoriented curves on surfaces

In 1980s Goldman introduced various Lie algebra structures on the free vector space generated by the free homotopy classes of closed curves in any orientable surface F. Naturally the universal enveloping algebra and the symmetric algebra of these Lie algebras admit a Poisson algebra structure....

Title: On triviality of the reduced Whitehead group
Let $D$ be a central division algebra over a field $E$. Denote by $D^*$ the nonzero elements of $D$. The reduced Whitehead group of $D$, $SK_1(D):=\{x\in D:{\rm Nrd}_D(x)=1 \}\big/[D^*,D^*]$. Aim of the talk is to show triviality of this group over certain Henselian valued...

Title: Topological results on Moduli of Curves

First I shall introduce the moduli space of curves over complex numbers.This has been a central object of study in Algebraic Geometry with connections in mathematical physics, number theory and complex dynamics. This is also the primary object of study in my research. I shall then talk about a...
