"Mathematical Logic Quarterly" [Em linha]. ISSN 0942-5616. Vol. 53, Nº 6 (2007), p. 1-200942-5616http://hdl.handle.net/10400.2/2838Suppose G is a definably connected, definable group in an o-minimal expansion of an ordered group. We show that the o-minimal universal covering homomorphism p:U->G is a locally definable covering homomorphism and π_1(G) is isomorphic to the o-minimal fundamental group π (G) of G defined using locally definable covering homomorphisms.engDefinable groupsO-minimal structuresUniversal coversjournal article
