# Measurable stochastics for brane calculus

### Abstract

© G. Bacci & M. Miculan.We give a stochastic extension of the Brane Calculus, along the lines of recent work by Cardelli and Mardare [8]. In this presentation, the semantics of a Brane process is a measure of the stochastic distribution of possible derivations. To this end, we first introduce a labelled transition system for Brane Calculus, proving its adequacy w.r.t. the usual reduction semantics. Then, brane systems are presented as Markov processes over the measurable space generated by terms up-to syntactic congruence, and where the measures are indexed by the actions of this new LTS. Finally, we provide a SOS presentation of this stochastic semantics, which is compositional and syntax-driven.
