The virtual ant introduced by Langton [Physica D 22 (1986) 120] has an interesting behavior, which has been studied in several contexts. Here we give a construction to calculate a...

We present a direct universal P system based on splicing. Our approach differs from those shown in previous papers as the P system we construct takes as input an encoding of anothe...

In this paper we consider the computation of reachable, viable and invariant sets for discrete-time systems. We use the framework of type-two effectivity, in which computations a...

Abstract. In this paper we show that membership in finitely generated submonoids is undecidable for the free metabelian group of rank 2 and for the wreath product Z ≀ (Z × Z). ...
