Some new inequalities for the Cebysev functional in terms of the first derivative and applications for Taylor's expansion and generalised trapezoid formula are pointed out.
We gave a new criterion for graphical partitions. We derive a new recursion formula, which allows the computation of the number g(n) of graphical partitions of weight n for up to ...
We consider the non-orthodox proof rules of hybrid logic from the viewpoint of topological semantics. Topological semantics is more general than Kripke semantics. We show that the...
We present a formal specification and verification approach for industrial product data bases containing Boolean logic formulae to express constraints. Within this framework, globa...
The problem of SPARQL query containment is defined as determining if the result of one query is included in the result of another for any RDF graph. Query containment is important...
