|Title:||Wiener-type topological indices of phenylenes|
|Abstract:||The Wiener index W of a phenylene (PH) has earlier been shown to depend in a mathematically exact manner on the Wiener indices of its hexagonal squeeze (HS) and inner dual (ID). We now examine the analogous dependency for a class of Wiener-type indices Wλ , where λ is a variable parameter (Wλ = W for λ= 1) is examined now. It is shown that some features of the dependency of W(PH) on W(HS) and W(ID) arc maintained for all values of λ , -5 ≤ λ ≤ +5 , whereas some are violated.|
