The paper deals with logically definable families of sets (or point-sets) of rational numbers. In particular we are interested whether the families definable over the real line wi...
We show that characteristic formulae for nite-state systems up to bisimulationlike equivalences (e.g., strong and weak bisimilarity) can be given in the simple branching-time temp...
Modern proof assistants such as Coq and Isabelle provide high degrees of expressiveness and assurance because they support formal reasoning in higher-order logic and supply explic...
: Since all the algebras connected to logic have, more or less explicitely, an associated order relation, it follows that they have two presentations, dual to each other. We classi...
