چکیده
|
Peripheral hosoya polynomial of a graph g is defined as, p h(g, λ) = σ k≥1 dp (g, k)λ^k , where dp (g, k) is the number of pairs of peripheral vertices at distance k in g. peripheral hosoya polynomial of composite graphs viz., g1 ×g2 the cartesian product, g1 +g2 the join, g1[g2] the composition, g1 ◦g2 the corona and g1{g2} the cluster of arbitrary connected graphs g1 and g2 are computed and their peripheral wiener indices are stated as immediate consequences.
