Abstract. We define a translation of aggregate programs to normal logic programs which preserves the set of partial stable models. We then define the classes of definite and str...
We construct a model without precipitous ideals but so that for each < 3 there is a normal ideal over 1 with generic ultrapower wellfounded up to the image of .
Higher-order narrowing is a general method for higher-order equational reasoning and serves for instance as the foundation for the integration of functional and logic programming. ...
We find a full system of invariants with respect to gauge transformations L g-1 Lg for third-order hyperbolic linear partial differential operators on the plane. The operators are...
Abstract. When developing statistical models of normal brain perfusion, two questions are of crucial interest: How well does an atlas describe normality and how sensitive is it at ...
