2341. Alf Onshuus Definability of Lie isomorphisms of groups definable in o-minimal expansions of the real field E-mail: Submission date: 8 February 2023 Abstract: In this paper, we study the relation between the category of real Lie groups and that of groups definable in o-minimal expansions of the real field (which we will refer to as definable groups). It is known ([Pi88]) that any group definable in an o-minimal expansion of the real field is a Lie group, and in [COP] a complete characterization of when a Lie group has a definable group which is Lie isomorphic to it was given. In this paper we continue the analysis by explaining when a Lie homomorphism between definable groups is a definable isomorphism. Mathematics Subject Classification: Keywords and phrases: |
