QUANTALE-VALUED GAUGE SPACES

We introduce a quantale-valued generalization of approach spaces in terms of quantale-valued gauges. The resulting category is shown to be topological and to possess an initially dense object. Moreover we show that the category of quantale-valued approach spaces defined recently in terms of quantale-valued closures is a coreflective subcategory of our category and, for certain choices of the qu...

Mushy magma beneath Yellowstone

[1] A recent prospective on the Yellowstone Caldera discounts its explosive potential based on inferences from tomographic studies which suggests a high degree of crystallization of the underlying magma body. In this study, we show that many of the first teleseismic P-wave arrivals observed at seismic stations on the edge of the caldera did not travel through the magma body but have taken longe...

Crowns were ceTnented onto the teeth using zinc cement, Fuji I, Vitrerner, or C&B Metabond, The samples were thermal-cycled fer 10,OOO cycles, They were then immersed in erythrosine solution, sectioned, and observed under a microscope. Microieakage analyses were performed using a O'4 point system. The data were sLatistica!ly analyzed. There were significant differenc...

Beneath-and-Beyond Revisited

It is shown how the Beneath-and-Beyond algorithm can be used to yield another proof of the equivalence of Vand H-representations of convex polytopes. In this sense this paper serves as the sketch of an introduction to polytope theory with a focus on algorithmic aspects. Moreover, computational results are presented to compare Beneath-and-Beyond to other convex hull implementations.
