A compositional query algebra for second-order logic and uncertain databases
World-set algebra is a variable-free query language for uncertain databases. It constitutes the core of the query language implemented in MayBMS, an uncertain database system. Thi...

Streams and strings in formal proofs
Streams are acyclic directed subgraphs of the logical ow graph of a proof representing bundles of paths with the same origin and the same end. The notion of stream is used to desc...

Sharp and Meager Elements in Orthocomplete Homogeneous Effect Algebras
We prove that every orthocomplete homogeneous effect algebra is sharply dominating. Let us denote the greatest sharp element below x by x↓. For every element x of an orthocomple...

Skolem Functions and Equality in Automated Deduction
We present a strategy for restricting the application of the inference rule paramodulation. The strategy applies to problems in first-order logic with equality and is designed to ...

Strong and uniform equivalence of nonmonotonic theories - an algebraic approach
We show that the concepts of strong and uniform equivalence of logic programs eneralized to an abstract algebraic setting of operators on complete lattices. Our results imply char...
