We propose a framework for the formal speci cation and veri cation of timed and hybrid systems. For timed systems we propose a speci cation language that refers to time only throug...
Impossible futures equivalence is the semantic equivalence on labelled transition systems that identifies systems iff they have the same "AGEF" properties: temporal logic...
Protocols for distributed systems make often use of random transitions to achieve a common goal. A popular example are randomized leader election protocols. We introduce probabilis...
