A logic program strongly quasi-terminates when only a finite number of distinct atoms (modulo variable renaming) are derivable from any given query and computation rule. This noti...
We show that the concepts of strong and uniform equivalence of logic programs eneralized to an abstract algebraic setting of operators on complete lattices. Our results imply char...
Abstract. In this paper we give some applications of weakly Picard operators theory to linear positive approximation operators, to difference equations with deviating argument and...
Proof assistants based on type theories, such as Coq and Lego, allow users to omit subterms on input that can be inferred automatically. While those mechanisms are well known, ad-h...
This paper extends our previous logical analysis of presumptions and burden of proof by studying the force of a presumption once counterevidence has been offered. In the jurisprude...
