The firing rule of Petri nets relies on a residuation operation for the commutative monoid of natural numbers. We identify a class of residuated commutative monoids, called Petri ...
Abstract. In this paper we attempt to formally study two very intuitive physical models: sealed envelopes and locked boxes, often used as illustrations for common cryptographic ope...
Filtering is a standard technique for fast approximate string matching in practice. In filtering, a quick first step is used to rule out almost all positions of a text as possib...
Abstract. This paper is concerned with the language inclusion problem for timed automata: given timed automata A and B, is every word accepted by B also accepted by A? Alur and Dil...
