Title: Moduli problems on nodal curves
Abstract: In this talk, I will mainly discuss the moduli of Higgs
bundles on nodal curves. First, I will talk about degenerations and
briefly overview a few moduli problems on a nodal curve, e.g., Picard,
moduli of vector bundles. Then, I will discuss a semistable
degeneration of the moduli of Higgs bundles and the extension of
Hitchin's symplectic form to this degeneration. If time permits, I will
discuss a few possible applications of this study.

Title: Grid graphs and their independence complexes
Abstract: A matching in a graph G is a collection of disjoint edges. The
matching complex of a graph G is a simplicial complex whose simplices
are matchings in G. Lately, grid graphs have been studied for their
homological and homotopical structures. In this talk, we will focus on
the grid graphs whose each block is a square. In particular, we will see
that the matching complexes of 3n grid graphs are homotopy equivalent to
a wedge of spheres. We will also see the comprehensive list of the
dimensions of spheres appearing in the wedge.
