| Abstract |
|---|
Three classes are introduced which are closely related to the class
included in the title. It is proven that the class
obtained from
by replacing axiom C4 by the commutativity of single substitutions can be considered as the abstract class in the ResekThompson theorem, thus it is representable by set algebras. Then the class
is defined and it is shown that the necessary and sufficient condition for neat embeddability of an algebra in CA
into
is the validity of the merry-go-round properties. Finally, the class
is introduced which class is a counterpart of
among the polyadic like algebras.
Key Words: Cylindric and quasi polyadic algebras representation
