The Triple-Pair Construction for Weighted -Pushdown Automata
Manfred Droste, Zoltán Ésik, Werner Kuich
Let S be a complete star-omega semiring and Sigma be an alphabet. For a weighted omega-pushdown automaton P with stateset 1...n, n greater or equal to 1, we show that there exists…
Commutative positive varieties of languages
Jorge Almeida, Zoltán Ésik, Jean-Éric Pin
We study the commutative positive varieties of languages closed under various operations: shuffle, renaming and product over one-letter alphabets.
*-Continuous Kleene -Algebras
Zoltán Ésik, Uli Fahrenberg, Axel Legay
We define and study basic properties of *-continuous Kleene -algebras that involve a *-continuous Kleene algebra with a *-continuous action on a semimodule and an infinite produ…
Proceedings 14th International Conference on Automata and Formal Languages
Zoltán Ésik, Zoltán Fülöp
The 14th International Conference Automata and Formal Languages (AFL 2014) was held in Szeged, Hungary, from the 27th to the 29th of May, 2014. The conference was organized by the…
Conway and iteration hemirings
M. Droste, Z. Esik, W. Kuich
Conway hemirings are Conway semirings without a multiplicative unit. We also define iteration hemirings as Conway hemirings satisfying certain identities associated with the finite…
Kleene Algebras and Semimodules for Energy Problems
Zoltán Ésik, Uli Fahrenberg, Axel Legay +1
With the purpose of unifying a number of approaches to energy problems found in the literature, we introduce generalized energy automata. These are finite automata whose edges are…
