Persistent Permutations, Fairness, Asymmetric Choice Petri Nets, and Ochmański’s Conjecture
摘要
Ochmański’s conjecture asserts that in a plain, pure and safe Petri net, and in the context of fairness, the existence of persistent permutations of finite computations allows one to deduce the existence of persistent permutations of infinite computations. In this paper, the conjecture is established for the class of pure and safe asymmetric choice Petri nets.
