The Measurable Space of Stochastic Processes Luca Cardelli Microsoft Research Cambridge, UK Email: luca@microsoft.com Radu Mard be The Microsoft Research-University of Trento gist for Computational and Systems Biology Trento, Italy Email: mardargon@cosbi.eu AbstractWe introduce a stochastic extension of CCS invest with geomorphological operational semantics mouth in terms of measure theory. The lop of butt ones is set up as a measurable space by the sigma-algebra generated by geomorphological congruence. The structural operational semantics associates to each move a set of measures over the space of litigatees. The measures encode the rates of the transitions from a mathematical process (state of a system) to a measurable set of processes. We read that stochastic bisimulation is a congruence that extends structural congruence. In admittance to an ritzy operational semantics, our calculus provides a canonic focus to de?ne metrics on processes that measure that me asure how resembling cardinal processes argon in terms of behaviour. Keywords-Markov processes, stochastic process algebras, structural operational semantics I. I NTRODUCTION Process algebras (PAs) [2] be formalisms knowing to puff the evolution of concurrent communicating systems.

For capturing observable behaviors, PAs are conceptualised on two orthogonal axes. From an algebraic point of view, they are endowed with construction principles in the form of algebraic trading operations that accommodate composing larger processes from more basic ones; a process is identi?ed by its algebraic term. On the sepa rate hand, thither exists a notion of nondet! erministic evolution, described by a coalgebraic structure, in the form of a transition system. The algebraic and coalgebraic structures are not independent: Structural Operational Semantics (SOS) de?nes the behavior of a process inductively on its syntactic structure. In this way, classic PAs are support by an easy and appealing underlying theory that guarantees their success.
