On binary operators and their derived relations
BIT, 1988Considering a list of abstract binary operations and relations, the author gives a sequence of seven simple to prove, but interesting and very useful theorems, which appear frequently in algebra and other fields. All results are known, but the approach is nice and appropriate for teaching, with a good generality.

Axiomatizability of algebras of binary relations
2007We present an overview of the axiomatizability problem of algebras of binary relations. The focus will be on the finite and non-finite axiomatizability of several fragments of Tarski’s class of representable relation algebras. We examine the step-by-step method for establishing finite axiomatizability and ultraproduct constructions for establishing non-
