Abstract

The intention of the paper is first to show the applicability of the general categorical framework of open maps to the setting of true concurrent models with dense time. In particular, we define a category of timed event structures and an accompanying path (sub)category of timed words. Then we use the framework of open maps to obtain an abstract notion of bisimulation which is established to be equivalent to the standard notion of timed bisimulation. Using the fact, we finally show decidability of timed bisimulation in the setting of finite timed structures.
