[HTML][HTML] Optimizing reachability sets in temporal graphs by delaying
A Deligkas, I Potapov - Information and Computation, 2022 - Elsevier
A temporal graph is a dynamic graph where every edge is assigned a set of integer time
labels that indicate at which discrete time step the edge is available. In this paper, we study …

Synchronizing weighted automata
S Iván - arXiv preprint arXiv:1403.5729, 2014 - arxiv.org
We introduce two generalizations of synchronizability to automata with transitions weighted
in an arbitrary semiring K=(K,+,*, 0, 1).(or equivalently, to finite sets of matrices in K^ nxn.) …

Schützenberger and Eilenberg theorems for words on linear orderings
N Bedon, C Rispal - Developments in Language Theory: 9th International …, 2005 - Springer
In the case of finite words, a Schützenberger theorem proves that the star-free sets are
exactly the languages recognized by finite aperiodic semigroups. This gives an algebraic …
