E-mail:

Submission date: 18 July 2007

Abstract:

We show that in o-minimal expansions of groups, the universal covering homomorphism of a definable group is a locally definable covering homomorphism and the o-minimal fundamental group defined using definable paths is isomorphism to the o-minimal fundamental group defined using locally definable covering homomorphisms.

Mathematics Subject Classification: 03C64; 20E99

Keywords and phrases: O-minimal structures, universal cover, definable groups.
