On semigroups and groupoids with minimal probabilistic spectrum
Carles Cardó
The equational probabilistic spectrum of a finite algebra is the set of probabilities with which equations are satisfied in the algebra. We study algebras with minimal spectrum, th…

Probabilistic equational spectrum, primality and approximation in finite algebras
Carles Cardó
We define the probability of an equation in a finite algebra as the proportion of tuples in its domain that satisfy it. We call the probabilistic spectrum of an algebra the set of…
