Fuzzy logics are many-valued logics that are well suited to reasoning in the context of
vagueness. They provide the basis for the wider field of Fuzzy Logic, encompassing diverse …

This paper is a contribution to Mathematical fuzzy logic, in particular to the algebraic study of
t-norm based fuzzy logics. In the general framework of propositional core and Δ-core fuzzy …

In this paper, we further study the variety of monadic nilpotent minimum (NM)-algebras and
their corresponding logic. In order to solve the drawback of monadic NM-algebras, we …

Starting from a decomposition result of monoidal t-norm-based logic (MTL)-chains as ordinal
sums, we focus our attention on a particular kind of indecomposable semihoops, namely …

It is well known that MTL satisfies the finite embeddability property. Thus MTL is complete wrt
the class of all finite MTL‐chains. In order to reach a deeper understanding of the structure of …

This paper investigates a quasi‐variety of representable integral commutative residuated
lattices axiomatized by the quasi‐identity resulting from the well‐known Wajsberg identity …

Resum En aquest article considerem el fenomen de la vaguetat com a problema lògic i les
diverses solucions que s' han proposat per a tractar-lo. D'entre totes elles defensem la …

We propose a method for characterizing the complexity of satisfiability and tautologicity of
equational theories of varieties of algebras by relying on their representability in the theory …

This thesis describes and examines some remarkable relationships existing between
seemingly quite different properties (algebraic, order-theoretic, and structural) of ordered …
