Title : Introduction to Lie group representations
Abstract: In the first of the two talks that I will give, I will introduce representations of Lie groups and prove a few basic properties of them. This will prepare ground for the Peter Weyl theorem to be discussed in the second lecture.
We have now a dedicated website where one can find the notes and resources from the past meets and announcements of the upcoming meetings:

Title: Spectral gap bounds for the simplicial Laplacian and an application
to random complexes
Abstract: Let L(G) denotes the Laplacian of a graph G. The second smallest
eigenvalue of L(G) is called the spectral gap. In this talk, we discuss
two spectral gap bounds for the reduced Laplacian of a simplicial complex.
As an application we prove that, if the spectral gap of the Laplacian of
skeleton of a simplicial complex is enough large, then its co-homology
vanishes up to certain dimensions. We also see an application of these
results in certain random complexes. This is a joint work with D.
Yogeshwaran.
