Regular positive bases
Regular Simplices and Gaussian Samples.
Regular triangles and isoclinic triangles in the Grassmann .
Regularization of star bodies by random hyperplane cut off
We present a general result on regularization of an arbitrary convex body (and more generally a star body), which gives and extends global forms of a number of well known local facts, like the low M*-estimates, large Euclidean sections of finite volume-ratio spaces and others.

Remplissage de l’espace euclidien par des complexes polyédriques d’orientation imposée et de rotondité uniforme
Nous donnons une méthode de construction de complexes polyédriques dans permettant de relier entre elles des grilles dyadiques d’orientations différentes tout en s’assurant que les polyèdres utilisés ne soient pas trop plats, y compris leurs sous-faces de toutes dimensions. Pour cela, après avoir rappelé quelques définitions et propriétés simples des polyèdres euclidiens compacts et des complexes, on se dote d’un outil qui permet de remplir de polyèdres -dimensionnels un ouvert en forme de tube...
