State hypergroups of automata
Jan Chvalina, Ludmila Chvalinová · Czech digital mathematics library · 1996
A functorial passage from the category of automata without outputs and their homomorphisms into the category of preorder hypergroups and strong homomorphisms based on the concept of inertial relation extended into apreording of a statě set is ušed for the describing of some basic properties of automata.Further, the relational hypergroup product is treated in connection with products of automata.
