素数幂的最优着色Tverberg定理
Optimal colored Tverberg theorems for prime powers
摘要：
Blagojević、Matschke和Ziegler的A型着色Tverberg定理在相交彩虹单形的个数为素数的条件下，为着色Tverberg问题提供了最优界。我们将这个结果推广到一个最优的，A型有色Tverberg定理的多集色点，这是有效的每个素数权力$r=p^k$。其中一个主要的新想法是取代周围的单纯形$Δ^N$，在原来的特沃伯格定理中使用的，由一个“简化的单纯形”的较小尺寸，并补偿这种减少，允许顶点重复出现在不同的彩虹单纯形的控制次数。在证明中使用的配置空间是组合伪流形，可以表示为多个棋盘复形。我们的主要拓扑工具是Eilenberg-Krasnoselskii理论的程度等变映射的非自由行动。
英文摘要：
The type A colored Tverberg theorem of Blagojević, Matschke, and Ziegler provides optimal bounds for the colored Tverberg problem, under the condition that the number of intersecting rainbow simplices is a prime number. We extend this result to an optimal, type A colored Tverberg theorem for multisets of colored points, which is valid for each prime power $r=p^k$. One of the principal new ideas is to replace the ambient simplex $Δ^N$, used in the original Tverberg theorem, by an "abridged simplex" of smaller dimension, and to compensate for this reduction by allowing vertices to repeatedly appear a controlled number of times in different rainbow simplices. Configuration spaces, used in the proof, are combinatorial pseudomanifolds which can be represented as multiple chessboard complexes. Our main topological tool is the Eilenberg-Krasnoselskii theory of degrees of equivariant maps for non-free actions.
