SECOND ANNOUNCEMENT OF TWO SPECIAL SESSIONS ON UNIVERSAL ALGEBRA AND LATTICE THEORY Note: You are receiving this because you are included on the Algebra ...
Hi! Consider a finite distributive lattice L. One may assume that L is a sublattice of a power set of some finite set. Denote by j1,..., j_r all with join...
A quick question. Could anybody drop me some references about characterizing the congruences ~ of an arbitrary algebra that make A/~ abelian, and those that...

When a formula p is in the theory TM(S) of the class M(S) of models of a set S of formulas, we call p a *consequence* of S. The dual relationship obtains when...
