Abstract

We show that if the state set Q of a synchronizing automaton A = 〈Q, Σ, δ〉 admits a linear order such that for each letter a ∈ Σ the transformation δ(-, a) of Q preserves this order, then A possesses a reset word of length |Q|-1. We also consider two natural generalizations of the notion of a reset word and provide for them results of a similar flavour.
