On commutativity of quasi-minimal groupsSlavko MoconjaFaculty of Mathematics, University of Belgrade, Belgrade, SerbiaAbstract: We investigate if every quasi-minimal group is abelian, and give a positive answer for a quasi-minimal pure group having a $\emptyset$-definable partial order with uncountable chains. We also relate two properties of a complete theory in a countable language: the existence of a quasi-minimal model and the existence of a strongly regular type. As a consequence we derive the equivalence of conjectures on commutativity of quasi-minimal groups and commutativity of regular groups. Keywords: quasi-minimal group; strongly regular type Classification (MSC2000): 03C45; 03C60; 20A15 Full text of the article: (for faster download, first choose a mirror)
