Principal congruence on the standard and distributive elements of a lattice
Cao Fa-sheng · Journal of Shandong University · 2010
A necessary condition for principal congruence on the standard elements of lattice L is given by analyzing the definition of the standard element and constructing a principal congruence formula.A decision condition for principal congruence on the distributive elements of lattice L is also characterized by constructing a principal congruence formula.
