Congruence properties of pseudocomplemented De Morgan algebras
We characterize which pseudocomplemented De Morgan algebras are congruence-permutable, congruence-uniform, have the principal join property, and have the principal congruence property. We use Priestley Duality for pseudocomplemented De Morgan algebras obtained by combining the known dualities of distributive p-algebras due to Priestley and for De Morgan algebras due to Cornish and Fowler. This is a joint work with H. P. Sankappanavar.
