Title: Hook Immanantal and Hadamard inequalities for q-Laplacians of trees

$\textbf{Abstract:}$ Let $T$ be a tree on $n$ vertices with Laplacian matrix $L$ and $q$-Laplacian $\mathcal{ L}_q$.
Let $\chi_k$ be the character of the irreducible representation of $\mathfrak{S}_n$ indexed by
the hook partition $k,1^{n-k}$ and let $\overline{ d}_k(L)$ be...

Title: On the dimension of the L^2[0, ∞) span of n linearly independent L^2_loc [0, ∞) functions

In this talk we explore the problem of determining the dimension of the L^2 [0, ∞)span of n linearly independent L^2_ loc [0, ∞) functions and the fascinating geometry associatedwith it. This problem appears in the context of Weyl’s limit classification problems of formallysymmetric differential...

Title: Extremal generalized $2d$-gons

*Generalized $2d$-gons* are point-line geometries whose incidence graph has diameter $2d$ and girth $4d$. A generalized $2d$-gon is said to have *order* $(s,t)$ if every line is incident with precisely $s+1$ points and if every point is incident with precisely $t+1$ lines. If $\...

Title: Graphs and Colourings

Abstract: Simply put, a graph is nothing but a set of points ("vertices"), along with edges which connect them. A planar graph is a special type of graph- one where the edges do not cross each other ( i.e., meet only at the vertices). In this talk, we will discuss an interesting problem in...

Title: Radon-Nikodym theorem and conditioning

This is the second lecture on this topic with the following:Abstact: Radon-Nikodym theorem of measure theory was proved in 1930 and A. N. Kolmogorov laid the foundation of modern probability in 1933 where the formal played a crucial role. In this Short Lecture Series in Mathematics (SLSM), we...
