Center node: "a complete quantitative deduction system for the bisimilarity distance on markov chains"
  Abstract: In this paper we propose a complete axiomatization of the bisimilarity#N#distance of Desharnais et al. for the class of finite labelled Markov chains.#N#Our axiomatization is given in the style of a quantitative extension of#N#equational logic recently proposed by Mardare, Panangaden, and Plotkin (LICS#N#2016) that uses equality relations $t \equiv_\varepsilon s$ indexed by#N#rationals, expressing that `$t$ is approximately equal to $s$ up to an error#N#$\varepsilon$'. Notably, our quantitative deduction system extends in a natural#N#way the equational system for probabilistic bisimilarity given by Stark and#N#Smolka by introducing an axiom for dealing with the Kantorovich distance#N#between probability distributions. The axiomatization is then used to propose a#N#metric extension of a Kleene's style representation theorem for finite labelled#N#Markov chains, that was proposed (in a more general coalgebraic fashion) by#N#Silva et al. (Inf. Comput. 2011).
