Content:Let G be a graph and let I = I(G) be its edge ideal. In this talk, we present the asymptotic linear function reg (I^s) as s>> 0 when G is a forest or a cycle and the initial value of s starting from which reg (I^s) attains its linear form. We also introduce a lower bound on regularity of I^s as s>0 for any graph G.
