Amalgamation Property for Varieties of BL-algebras Generated by One Chain with Finitely Many Componposed (up to isomorphism) as an ordinal sum of non-trivial Wajsberg hoops - called components - with the first bounded. In this paper we study the amalgamation property for the varieties of BL-algebras generated by one BL-chain with finitely many components.

Experimental Investigation of Sufficient Criteria for Relations to Have Kernels,ive and symmetric, to be progressively finite, to be bipartite and to satisfy Richardson’s criterion. The numerical data, obtained by the evaluation of relation-algebraic problem specifications using .  show that even the most general of them is very far away from a characterisation of the class of directed graphs/relations having kernels.

-Multisemigroups, Modal Quantales and the Origin of Locality,nd codomain axioms of modal quantales. Our results yield new insights on the origin of locality in modal semirings and quantales. They also yield construction principles for modal powerset quantales that cover a wide range of models and applications.

,Relation-Algebraic Verification of Borůvka’s Minimum Spanning Tree Algorithm,ess of a sequential version of Borůvka’s minimum spanning tree algorithm. This is the first formal proof of correctness for this algorithm. We also discuss new abstractions that make it easier to reason about weighted graphs.

Free Modal Riesz Spaces are Archimedean: A Syntactic Proof,ttices) endowed with a positive linear 1–decreasing operator, and have found application in the development of probabilistic temporal logics in the field of formal verification. All our results have been formalised using the Coq proof assistant.
