    Free iterative and iteration K-semialgebras

    We consider algebras of rational power series over a finite alphabet Σ with coefficients in a commutative semiring K and characterize them as the free algebras in various classes of algebraic structures.

    On Iteration Semiring-Semimodule Pairs

    Conway semiring-module pairs and iteration semiring-semimodule pairs were shown to provide an axiomatic basis to automata on ω -words in [Bloom, Esik: Iteration Theories, Springer, 1993]. In this paper, we sho...

    Locally Closed Semirings

     We call a semiring S locally closed if for all a ∈ S there is some integer k such that 1 + a + ⋯ + a k  =1 + a + ⋯ + a k + 1 . In any locally...

    Semitopological semirings and pushdown automata

    This paper deals with algebraic power series over a commutative semiringA. A characteristization result states that a power series is algebraic if and only if it is the behavior of a proper pushdown automaton.
