If \(\kappa > \aleph_0\) then \(\kappa \to(\kappa,\operatorname{Top}K_\kappa)^2\), i.e., every graph on \(\kappa\) vertices contains either an independent set of \(\kappa\) vertices, or a topological \(K_\kappa\), iff \(\kappa\) is regular and there is no \(\kappa\)-Suslin tree. Concerning the statement \(\omega_2\to(\operatorname{Top}K_{\omega_2})^2_\omega\), i.e., in every coloring of the edges of \(K_{\omega_2}\) with countably many colors, there is a monochromatic topological \(K_{\omega_2}\), both the statement and its negation are consistent with the Generalized Continuum Hypothesis.

不可数完整图的着色中的单色拓扑完整图

如果\(\ kappa> \ aleph_0 \),\(\ kappa \ to(\ kappa,\ operatorname {Top} K_ \ kappa)^ 2 \),即\(\ kappa \)顶点上的每个图都包含一个独立的\(\ kappa \)顶点集或拓扑\(K_ \ kappa \),如果iff \(\ kappa \)是常规的,则没有\(\ kappa \)- Suslin树。关于语句\(\ omega_2 \ to(\ operatorname {Top} K _ {\ omega_2})^ 2_ \ omega \),即\(K _ {\ omega_2} \)的边缘的每种着色都有很多颜色,存在单色拓扑\(K _ {\ omega_2} \),该陈述及其否定词均与广义连续体假说一致。
