A General Framework for Probabilistic Characterizing Formulae
Abstract. Recently, a general framework on characteristic formulae was proposed by Aceto et al. It offers a simple theory that allows one to easily obtain characteristic formulae o...

A Spectrum of Behavioral Relations over LTSs on Probability Distributions
Probabilistic nondeterministic processes are commonly modeled as probabilistic LTSs (PLTSs, a.k.a. probabilistic automata). A number of logical characterizations of the main behavi...

A Class of Probabilistic Automata with a Decidable Value 1 Problem
The value 1 problem is a decision problem for probabilistic automata on finite words: given a probabilistic automaton A, are there words accepted by A with probability arbitraril...

Equivalence of Labeled Markov Chains
We consider the equivalence problem for labeled Markov chains (LMCs), where each state is labeled with an observation. Two LMCs are equivalent if every finite sequence of observat...

Conditional Automata: A Tool for Safe Removal of Negligible Events
Abstract. Polynomially accurate simulations [19] are relations for Probabilistic Automata that require transitions to be matched up to negligible sets provided that computation len...

Probability and Nondeterminism in Operational Models of Concurrency
We give a brief overview of operational models for concurrent systems that exhibit probabilistic behavior, focussing on the interplay between probability and nondeterminism. Our su...

Probabilistic Automata on Finite Words: Decidable and Undecidable Problems
Abstract. This paper tackles three algorithmic problems for probabilistic automata on finite words: the Emptiness Problem, the Isolation Problem and the Value 1 Problem. The Empti...

Compositionality for Probabilistic Automata
We establish that on the domain of probabilistic automata, the trace distribution precongruence coincides with the simulation preorder.

Probabilistic Automata: System Types, Parallel Composition and Comparison
We survey various notions of probabilistic automata and probabilistic bisimulation, accumulating in an expressiveness hierarchy of probabilistic system types. The aim of this paper...
