Jerzy Płonka, regular identity, P-compatible identity, Płonka sum, P-dispersionAbstract
We would like to present and discuss certain ideas developed by Jerzy Płonka. Jerzy Płonka was a Polish algebraist whose scientific interests included equational logics considered in terms of the structure of the identities that define them. In this paper, we present two constructions by Jerzy Płonka, which served as tools in his work on semantics for classes determined by the so-called-compatible and regular identities. We are referring to the dispersion and the Płonka sum.
