Title: Regularity of binomial edge ideals.
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.
