Title: A few methods to compute De-Rham cohomology

We will discuss some methods to compute the De-Rham Cohomology of smooth manifolds. We will discuss how to apply Mayer-Vietoris (which is the analogue of Van-Kampen Theorem for (co)homology).

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: Geometric models of coverings of graphs

We shall discuss covering spaces of graphs, leading to facts about subgroups of free groups.We shall then construct geometric models, inspired by these graphs,and analyze some concrete examples.
