Inherited Properties of Effect Algebras Preserved by Isomorphisms

Jan Paseka, Zdenka Riečanová


We show that isomorphism of effect algebras preserves properties of effect algebras derived from effect algebraic sum ? of elements. These are partial order, order convergence, order topology, existence of states and other important properties. However, there are properties of effect algebras for which the preservation of the ?-operation is not substantial and they need not be preserved.
