Computation of protein geometry and its applications: Packing and function predictionJan 14 2006This chapter discusses geometric models of biomolecules and geometric constructs, including the union of ball model, the weigthed Voronoi diagram, the weighted Delaunay triangulation, and the alpha shapes. These geometric constructs enable fast and analytical ... More
Order bornological spaces and order ultrabornological spacesAug 31 2015Ordered locally convex spaces is an important classes of spaces in the theory of ordered topological vector spaces just as locally convex spaces in the theory of topological vector spaces. Some special classes of ordered locally convex spaces such as ... More
Approximation faible pour les 0-cycles sur un produit de variétés rationnellement connexesSep 09 2014Mar 11 2015Consider weak approximation for 0-cycles on a smooth proper variety defined over a number field, it is conjectured to be controlled by its Brauer group. Let $X$ be a Ch\^atelet surface or a smooth compactification of a homogeneous space of a connected ... More
Principe local-global pour les zéro-cycles sur certaines fibrations au-dessus d'une courbe : IJun 13 2010May 05 2011Let $X$ be a smooth projective variety over a number field, fibered over a curve, with geometrically integral fibers. We prove that, supposing the finiteness of $\sha(Jac(C))$, if the fibers over a generalised Hilbertian subset satisfy the Hasse principle ... More
