本文证明了:对于没有坏K4剖分的图G=(V,E),对于$B\in {\bfZ}_{+}^{V\cup E}$,其b-稳定集多面体是由图G的顶点、边和奇圈所确定的约束系统所决定的.我们还证明了该系统是完全对偶积分的。这与t-完美图有关。
We prove that for a graph G=(V,E) without bad K4 subdivision, and for $b\in {\bf Z}_{+}^{V\cup E}$, the b-stable set polytope is determined by the system of constraints determined by the vertices, edges, and odd circuits. We also prove that this system is totally dual integral. This relates to t-perfect graphs.
