We introduce a class of coalgebraic models and a family of modal logics that support the specication of spatial properties of distributed applications. The evaluation of a formul...
Abstract. We study a weakening of the notion of logical relations, called prelogical relations, that has many of the features that make logical relations so useful but having furth...
This article studies preservation of certain algebraic properties of propositional logics when combined by fibring. The logics analyzed here are classified in protoalgebraic, eq...
