讲座题目：Trace semantics for propositional dynamic logics

讲座摘要：Other than relation semantics, there is a natural trace semantics for propositional dynamic logics, in which actions are sets of finite sequences, not binary relations. The two kinds of semantics are equivalent when only composition, choice and iteration of actions are concerned. However, intersection would make a difference. This paper presents a complete axiomatization of the logic in trace semantics for the language with composition, intersection and choice.
