Abstract :
Omega polynomial of a graph G is defined, on the ground of opposite edge strips ops: ЕG;xЖ И. P c. mЕG;cЖxc, where m(G, c)is the number of ops strips of length c. The Sadhana polynomial Sd(G; x)can also be calculated by ops counting. In this paper we compute these polynomials for polyomino chains of 4k-cycles. Also by using Omega polynomial we can compute the (edge) PIe polynomial for this graph.
Keywords :
