ON ENVELOPING TYPE-DEFINABLE STRUCTURES 1025. Theorem. Let Ga be an A-type-definable group in a small and simple univers. (i) If Ga is included in some ...
Abstract. We observe simple links between equivalence relations, groups, fields and groupoids (and between preorders, semi-groups, rings and categories), ...
We show that a ∅-type-definable group in a small structure is the conjunction of definable groups, and extend the result to semi-groups, fields, rings, ...

1. if GA is included in some definable set X such that boundedly many translates of GA cover X, then GA is the conjunction of definable groups.
We show that a 0-type-definable group in a small structure is the conjunction of definable groups, and extend the result to semi-groups, fields, rings, ...
