Towards a Causal Semantics for Brane Calculi

Description

Brane Calculi are a family of biologically inspired process calculi, proposed in [6] to model the interactions of dynamically nested membranes. We propose a semantics that describes the causal dependencies occurring between the reactions of a system described in Brane Calculi. We investigate the basic properties that are satisfied by such a semantics. The notion of causality turns out to be quite relevant for biological systems, as it permits to point out which events occurring in a biological pathway are necessary for another event to happen.
