Three IndicesCalculationof Certain Crown Molecular Graphs

Journal Title: JOURNAL OF ADVANCES IN MATHEMATICS - Year 2014, Vol 9, Issue 6

Abstract

As molecular graph invariant topological indices, harmonic index, zeroth-order general Randic index and Co-PI index have been studied in recent years for prediction of chemicalphenomena. In this paper, we determine the harmonic index, zeroth-order general Randic index andCo-PI indexof certain r-crown molecular graphs.

Theory of Linear Hahn difference equations

Hahn introduced the dierence operator Dq,wf (t)=(f(qt+w)-f(t))/(t(q-1)+w) in 1949, where  0<q<1 and w>0  are fixed real numbers. This operator extends the classical differance operator Vwf(t) = (f(t +...
