Query Languages for Real Number Databases Based on Descriptive Complexity over Rcan be done in such a way that the logical description exactly reflects the computational complexity of a query. The latter might circumvent a problem appearing in some of the former approaches dealing with semi-algebraic databases (see [.] , [.]), where the use of first-order logic over real-closed

Computing and Comparing Semantics of Programs in Four-Valued Logicserent values of the parameter. The semantics proposed by Fitting corresponds to the value false. We also show that our approach captures and extends the usual semantics of conventional logic programs thereby unifying their computation.

On the Complexity of Recognizing the Hilbert Basis of a Linear Diophantine Systemunary and therefore the previously known coNP-completeness result was unusable. Moreover, we prove that, given a linear Diophantine system and a set of solutions, asking whether this set constitutes the Hilbert basis of the system, is also coNP-complete in the strong sense, answering this way an ope
