Bernstein algebras with a lattice isomorphism that does not preserve the nucleus

摘要

In this paper Bernstein algebras and isomorphisms between the lattices of subalgebras are studied. Since it is not true, in general, that lattice isomorphisms of Bernstein algebras keep the nucleus of the weight homomorphism, the present aim is to study Bernstein algebras having a lattice isomorphism that does not keep the nucleus
