Congruences on the symmetric extended bounded distributive lattice and its applications
Congwen Luo · 2010
In this paper we give the definition of a symmetric extended bounded distributive lattice,namely it is a bounded distributive lattice with an unary operation satisfied certain conditions.We get the equational description of the principal congruence of the symmetric extended bounded distributive lattices,and also its complementary.Furthermore,the subdirectly irreducibility is studied.
