## Abstract We study the class of Sperner spaces, a generalized version of affine spaces, as defined in the language of pointline incidence and line parallelity. We show that, although the class of Sperner spaces is a pseudoβelementary class, it is not elementary nor even βοΈ~β__Ο__~βaxiomatizable.
The notion of unification for fuzzy sets in fuzzy logic programming is explored in this article from the standpoint of a theoretical framework based on first-order probabilistic modal logic. The fundamental difference between the latter perspective and other approaches described in the literature li
