Regularity comparison of symbolic powers, integral closure of powers and powers of edge ideals

Abstract

We study the regularity of small symbolic powers and integral closure of small powers of edge ideals. We also prove that the regularity of integral closure of powers of edge ideals of graphs with at most two odd cycles is the same as the regularity of their powers.
