Stability of the Theory of Existentially Closed S-acts over a Right Coherent Monoid S
Let LS denote the language of (right) S-acts over a monoid S and let ΣS be a set of sentences in LS which axiomatises S-acts. A general result of model theory says that ΣS has a model companion, denoted by TS , precisely when the class E of existentially closed S-acts is axiomatisable and in this case, TS axiomatises E . It is known that TS exists if and only if S is right coherent. Moreover, b...
متن کاملCongruence Lattices of Uniform Lattices
A lattice L is uniform, if for any congruence Θ of L, any two congruence classes A and B of Θ are of the same size, that is, |A| = |B| holds. A classical result of R. P. Dilworth represents a finite distributive lattice D as the congruence lattice of a finite lattice L. We show that this L can be constructed as a finite uniform lattice.
متن کاملCovers for S-acts and Condition (a) for a Monoid S
A monoid S satisfies Condition (A) if every locally cyclic left S-act is cyclic. This condition first arose in Isbell’s work on left perfect monoids, that is, monoids such that every left S-act has a projective cover. Isbell showed that S is left perfect if and only if every cyclic left S-act has a projective cover and Condition (A) holds. Fountain built on Isbell’s work to show that S is left ...
متن کاملDistributive Congruence Lattices of Congruence-permutable Algebras
We prove that every distributive algebraic lattice with at most א1 compact elements is isomorphic to the normal subgroup lattice of some group and to the submodule lattice of some right module. The א1 bound is optimal, as we find a distributive algebraic lattice D with א2 compact elements that is not isomorphic to the congruence lattice of any algebra with almost permutable congruences (hence n...
متن کاملCongruence Lattices of Congruence Semidistributive Algebras
Nearly twenty years ago, two of the authors wrote a paper on congruence lattices of semilattices [9]. The problem of finding a really useful characterization of congruence lattices of finite semilattices seemed too hard for us, so we went on to other things. Thus when Steve Seif asked one of us at the October 1990 meeting of the AMS in Amherst what we had learned in the meantime, the answer was...
