The Crossing Number of Cartesian Products of Stars with 5-vertex Graphs Ⅱ

摘要

The crossing number of cartesian products of paths and cycles with 5-vertex graphs mostly are known,but only few cartesian products of 5-vertex graphs with star K1,n are known.In this paper,we will extent those results,and determine the crossing numbers of cartesian products of two 5-vertex graphs with star K1,m.
