,Ω-branching programs of bounded width,We investigate the question whether equipping some of the nodes of a width-bounded branching program with devices for evaluating Boolean functions does increase its computational power. In contrast to the situation for unbounded width branching programs, in the bounded width case we have to negate this question generalizing a result of Barrington.

A predicate calculus with control of derivations,A fragment of classical predicate calculus which does not contain rules for contraction is defined. It is shown to be decidable and yet propositionally complete. A semantics which reflects its constructive character is developed.

,Resisting Racism in the Academy: ‘,’, the property of recursively covered programs and goals. We show that, for programs and goals that are call-consistent, even and recursively covered, SLDNF-resolution computes a complete set of ground answers. We then propose further generalized conditions that ensure that SLDNF-resolution is flound

We introduce semi-unification via the typability problem for polymorphic recursive definitions, present a reduction calculus for semi-unification problems, and discuss partial results on termination of reductions. We prove decidability of semi-unification in two v

Both define the same mathematical object, but we show that they have a completely different algorithmic content. The essential of the difference appears in the operational properties of two programs: t
