A note on the lattice definability of Bernstein algebras (Q1208311)

First, the author lists known definitions and theorems about Bernstein algebras. Then she defines lattice isomorphism of an algebra onto another one, and proves the following theorems: If two exclusive Bernstein algebras are lattice isomorphic, they have the same type. -- If two normal Bernstein algebras are lattice isomorphic, they have the same type.
