Bialgebraic Semantics for Logic Programming

Filippo Bonchi ; Fabio Zanasi.

Bialgebrae provide an abstract framework encompassing the semantics of different kinds of computational models. In this paper we propose a bialgebraic approach to the semantics of logic programming. Our methodology is to study logic programs as reactive systems and exploit abstract techniques&nbsp;[&hellip;]

Convexity via Weak Distributive Laws

Filippo Bonchi ; Alessio Santamaria.

We study the canonical weak distributive law $\delta$ of the powerset monad over the semimodule monad for a certain class of semirings containing, in particular, positive semifields. For this subclass we characterise $\delta$ as a convex closure in the free semimodule of a set. Using the abstract&nbsp;[&hellip;]

The Theory of Traces for Systems with Nondeterminism, Probability, and Termination

Filippo Bonchi ; Ana Sokolova ; Valeria Vignudelli.

This paper studies trace-based equivalences for systems combining nondeterministic and probabilistic choices. We show how trace semantics for such processes can be recovered by instantiating a coalgebraic construction known as the generalised powerset construction. We characterise and compare the&nbsp;[&hellip;]
