Probabilistic models for true-concurrency: branching cells and distributed probabilities for event structures
Résumé
This paper is devoted to probabilistic models for concurrent systems under their true-concurrency seman- tics. Here we address probabilistic event structures. We consider a new class of event structures, called locally finite, that extend confusion-free event structure. In locally finite event structures, maximal configurations can be tiled with branching cells: branching cells are minimal and finite sub-structures capturing the choices performed while scanning a maximal configuration. The probabilistic event structures that we introduce have the property that concurrent processes are independent in the probabilistic sense.
