报告摘要：In this talk we present some best constants for the Hardy-Littlewood maximal operators defined on finite undirected and directed graphs and spherical maximal operators on finite undirected graphs on the \ell^p spaces, weak \ell^p spaces and BV_p spaces. Here BV_p spaces are the set of all functions of bounded p-variation on the graph. This is joint work with Qingying Xue, Xiao Zhang and Huiyun Zhang.
