A note on the independence numberof strong products of odd cycles

摘要

The determination of the zero-capacity of a noisy channel have inspired researches of the independence number of the strong product of odd cycles. The independence number for two infinite families of the strong product of three odd cycles is considered in this paper. In particular, we present the independence number of C_7 □ C_9 □ C_(2k+1) and an upper bound on the independence number of C_(13) □ C_(13) □ C_(2k+1). The results are partially obtained by a computer search.
