We prove several decidability and undecidability results for -PN, an extension of P/T nets with pure name creation and name management. We give a simple proof of undecidability of...
The trace subshift of a cellular automaton is the subshift of all possible columns that may appear in a space-time diagram. We prove the undecidability of a rather large class of p...
In this paper, we study turn-based quantitative multiplayer non zero-sum games played on finite graphs with reachability objectives. In this framework each player aims at reaching...
We prove the completeness of the combination of ordered resolution and factoring for a large class of non-liftable orderings, without the need for any additional rules like satura...
To enable a rich attribute-based authorization system, it is desirable that a large number of user attributes are available, possibly provided by multiple entities. The user may b...
