This book presents a guide to the extensive literature on the topic of semirings and includes
a complete bibliography. It serves as a complement to the existing monographs and a point …

Given an algebra M we may adjoin an isolated zero to form an algebra Mo satisfying all
identities u≈ v true in M for which u and v contain the same variables. Drawing on the …

The paper describes the isomorphic lattices of quasivarieties of commutative quasigroup
modes and of cancellative commutative binary modes. Each quasivariety is characterised by …

Convex subsets of affine spaces over the field of real numbers are described by so-called
barycentric algebras. In this paper, we discuss extensions of the geometric and algebraic …

This thesis focuses on a wide family of logics whose common feature is to admit a syntactic
definition based on specific variable inclusion principles. This family has been divided into …

Logics of significance have been proposed in an attempt to overcome the shortcomings of
classical logic as a model of reasoning in the presence of nonsignificant (eg, meaningless …

Let be a signature without-ary operation symbols and the category of semilattices. Then,
after defining and investigating the categories, of inductive systems of-algebras over all …

The Mal'tsev product of two varieties of similar algebras is always a quasivariety. We
consider the question of when this quasivariety is a variety. The main result asserts that if VV …
