O-极小结构中可定义群的覆盖

Covers of groups definable in o-minimal structures

Mario J. Edmundo

摘要:

本文发展了O-极小结构$\N$中具有可定义选择的Hausdorff真$\bigvee $ -可定义流形的覆盖理论.特别地,我们证明了给定一个$\N$ -可定义连通的$\N$ -可定义群$G$,我们在严格正确$\bigvee $ -可定义群的范畴中有$1\to π_1(G)\to \tilde{G}\stackrel{p}\to G\to 1$,它具有严格正确$\bigvee $ -可定义同态,其中$π_1(G)$是$G$的o-极小基本群.

英文摘要:

We develop in this paper the theory of covers for Hausdorff properly $\bigvee $-definable manifolds with definable choice in an o-minimal structure $\N$. In particular, we show that given an $\N$-definably connected $\N$-definable group $G$ we have $1\to π_1(G)\to \tilde{G}\stackrel{p}\to G\to 1$ in the category of strictly properly $\bigvee $-definable groups with strictly properly $\bigvee $-definable homomorphisms, where $π_1(G)$ is the o-minimal fundamental group of $G$.
