Abstract:In this paper introduced the method of minimum immovable edges for the calculation of color function. And according to the decompose method of similarity and difference, it introduced the principle that the color number reverse never happens. Through the analysis and calculation with this method and principle, it calculated the color number of 5-cycle configuration in graph T. And then introduced an equivalent definition that the coefficient a in part A is bigger than zero, which will be the same as the reducibility of n-cycle configuration in the graph T. Finally carried out the proof that the coefficient a in part A is bigger than zero for 5-cycle configuration in graph T. | |||
