Equivalence Checking Problem for Finite State Transducers

Lecture Notes in Computer Science. 2015. Vol. 9270. P. 208-221.
Zakharov V.A.

Finite state transducers over semigroups can be regarded as a formal model of sequential reactive programs. In this paper we introduce a uniform tech- nique for checking e ectively functionality, k-valuedness, equivalence and inclusion for this model of computation in the case when a semigroup these transducers op- erate over is embeddable in a decidable group.
