有色Tverberg问题的最优界

Optimal bounds for the colored Tverberg problem

Pavle V. M. Blagojević, Benjamin Matschke, Günter M. Ziegler

摘要:

证明了一个“Tverberg型”多重交定理。它通过添加颜色约束,加强了1966年的原始Tverberg定理的素数情况,以及Barany et al.(1980)的拓扑Tverberg定理。它也为Barany & Larman(1992)的(拓扑)有色Tverberg问题提供了一个改进的界,该界在素数情形下是紧的,在一般情形下是渐近最优的。证明是基于相对等变阻塞理论。

英文摘要:

We prove a "Tverberg type" multiple intersection theorem. It strengthens the prime case of the original Tverberg theorem from 1966, as well as the topological Tverberg theorem of Barany et al. (1980), by adding color constraints. It also provides an improved bound for the (topological) colored Tverberg problem of Barany & Larman (1992) that is tight in the prime case and asymptotically optimal in the general case. The proof is based on relative equivariant obstruction theory.
