Abstract

We consider the varieties P2m,0 of Ockam algebras, i.e., those in which for any element x of the dual space X of the algebra, the equality g2m(x) = x holds.  We show that these varieties have specific properties and consequently are more tractable than the others.  In particular, all the subvarieties of P2m,0 can be characterised by axioms that are self-dual.  We apply these properties to the description of P6,0 and P10,0.
