چکیده
|
In this paper, kekule structures of benzenoid chains are considered. it has been shown that the coefficients of a b_n (x) morganvoyce polynomial equal to the number of k-matchings (m(g,k)) of a path graph which has n=2n+1 points. furtermore, two relations are obtained between regularly zigzag nonbranched catacondensed benzenid chains and morganvoyce polynomials and between regularly zig-zag nonbranched catacondensed benzenid chains and their corresponding caterpillar trees.
