We analyze when the model of probabilistic automata has decidable properties, when restricting the ambiguity. The notion of ambiguity is usually used in weighted automata or transducers, but we follow a recent paper by Fijalkow, Riveros and Worrell, which introduced this approach. We do not solve everything but our decidability results rely unexpectedly on Schanuel's conjecture and we provide some geometric intuition behind the hardness of the problem. |
