Abstract. We prove that uniform and semi-uniform families of P systems with active membranes using only communication and nonelementary division rules are not computationally unive...

A family of subsets C of [n] def = {1, . . . , n} is (r, t)exclusive if for every S ⊂ [n] of size at least n − r, there exist S1, . . . , St ∈ C with S = S1∪S2∪· · · ...
In [6] Besnard and Schaub elaborated a novel approach to paraconsistent reasoning which lead to a family of paraconsistent consequence relations. In a sense these try to safeguard...
This work is devoted to stationary optimal control problems with polygonal constraints on the components of the state. Existence of Lagrange multipliers, of different regularity, i...
The paper presents a new schematization of in nite families of terms called the primal grammars, based on the notion of primitive recursive rewrite systems. This schematization is...
