This paper studies the logic of a dyadic modal operator for being obliged to meet a condition ρ before a condition δ becomes true. Starting from basic intuitions we arrive at a s...

Hybrid logics internalize their own semantics. Members of the newer family of justification logics internalize their own proof methodology. It is an appealing goal to combine thes...
Abstract. We describe a model-checking based approach to verification of programs written in the agent programming language Dribble. We define a logic (an extension of the branch...
A method is described for proving “always possibly” properties of specifications in formalisms with linear-time trace semantics. It is shown to be relatively complete for TLA...
Abstract. In formal verification of hybrid systems, a big challenge is to incorporate continuous flow dynamics in a discrete framework. Our previous work proposed to use nonstand...
