Abstract(in English) | The skew product of graphs is introduced in Y.Shibata and Y.Kikuchi, Graph products based on the distance in graphs, IEICE Trans. Fundamentals, E83-A, 3(2000) 459-464. We introduce a new class of graphs using the skew product. This class is the skew product of a hypercube and a path, where the length of the path is greater than the dimension of the hypercube by one. We show that if n is odd, then the skew product of the n dimensional hypercube and the path of length n+1 is isomorphically factorized by the n-dimensional butterfly. We introduce the swallowtail graph and the twisted swallowtail graph that play an important role in the proof of the above statement. Moreover, we show that if n is even, then the skew product of the n dimensional hypercube and the path of length n+1 is decomposed by n/2 n-dimensional butterflies and 2^n paths of length n+1. |
