• Formal Languages and Automata V: Conway Semiring-Semimodule Pairs and Finite Automata

  ... pair is a pair consisting of a Conway semiring and a semimodule that satises the sum-omega equation and the product-omega equation. We dene these Conway semiring-semimodule pairs and state some of their important properties. Then we introduce nite automata over quemirings and prove a Kleene Theorem. Furthermore, we introduce linear systems over quemirings as a generalization of regular grammars with nite and innite derivations, and connect certain solutions ...
