色轨道多项式的性质及其应用

Property and application of the chromatic orbit polynomial

将Pólya计数定理和计算图色数的色多项式结合,对P-图和Pn图的色轨道多项式及色本原多项式进行研究,给出其一些新的性质.并以戊烷分子为例,计算其分子能态数.

By combining Pólya theorem and the chromatic polynomial, chromatic orbit polynomial and primitive chromatic polynomial of P-graph and Pn graph were studied.The new properties of them were put forward.With pentane molecular as example,its molecular energy state number was calculated.
