In the axiomatization of relation algebras by Chin and Tarski certain elements are called fight ideals. Aiming at applications in the relational theory of graphs and programs, we call such ideals 'points' and investigate an additional point axiom. First we prove a point insertion theorem. Then a rep
## Abstract We give a simple new construction of representable relation algebras with nonβrepresentable completions. Using variations on our construction, we show that the elementary closure of the class of completely representable relation algebras is not finitely axiomatizable (Β© 2009 WILEYβVCH V
We use relations between Galois algebras and monoidal functors to describe monoidal functors between categories of representations of finite groups. We pay special attention to two kinds of these monoidal functors: monoidal functors to vector spaces and monoidal equivalences between categories of re
