| 摘 要： | 混合超图的上、下色数与C-超边和D-超边数有着必然联系.一般地,增加C-超边会使下色数χ（H）增加,增加D-超边会使上色数χ-（H）减小.本论文对D-完全一致混合超图的上色数进行了研究,并得到一些初步的结果.

| Abstract: | The upper chromatic number and the lower chromatic number of mixed hypergraphs closely relacted with the number of its C-hyperedges and D-hyperedges.In general,adding one C-edges to H can increase χ(H) and adding one D-edge can decrease χ-(H),where H is a mixed hypergraph,χ(H) is the lower chromatic number of H and χ-(H) is the upper chromatic number of H.In this artical,we study on the upper chromatical number of D-complete Uniform mixed hypergraphs and attain some initial results for this. |
