Abstract: This talk is going to be about the regularity of binomial edge ideals. There are two regularity upper bound conjectures for binomial edge ideals. We will be discussing these two conjectures. Saeedi Madani and Kiani conjectured that the regularity of the binomial edge ideal of a graph is bounded above by the number of cliques of that graph. Hibi and Matsuda conjectured that the regularity of the binomial edge ideal of a graph is bounded above by the degree of h polynomial of that graph. We will also be discussing the regularity of binomial edge ideals of Cohen-Macaulay bipartite graphs.

Later, we shall discuss the notions related to symplectic and orthogonal parabolic Higgs bundles and their moduli space, and study the spectral data and describe the Hitchin fibration in terms of spectral data.
