摘要
设G是一个图,m i,j (G), i,j≥1,为G的边数uv,使{d v (G), d u (G)} = {i,j}。G的M多项式是M (G;x, y) = (cid:80) i≤j m i,j (G) x i y j。给出了计算任意图族m多项式的一般方法。对于图的顶点具有2度和p度,且p≥3的情况,以及此类平面图,进一步发展了该方法。用化学图族说明了这种方法。
How to Compute the M-Polynomial of (Chemical) Graphs
Let G be a graph and let m i,j ( G ), i, j ≥ 1, be the number of edges uv of G such that { d v ( G ) , d u ( G ) } = { i, j } . The M-polynomial of G is M ( G ; x, y ) = (cid:80) i ≤ j m i,j ( G ) x i y j . A general method for calculating the M-polynomials for arbitrary graph families is presented. The method is further developed for the case where the vertices of a graph have degrees 2 and p , where p ≥ 3, and further for such planar graphs. The method is illustrated on families of chemical graphs.
期刊介绍:
MATCH Communications in Mathematical and in Computer Chemistry publishes papers of original research as well as reviews on chemically important mathematical results and non-routine applications of mathematical techniques to chemical problems. A paper acceptable for publication must contain non-trivial mathematics or communicate non-routine computer-based procedures AND have a clear connection to chemistry. Papers are published without any processing or publication charge.
