Initially released in 1917. This quantity from the Cornell college Library's print collections was once scanned on an APT BookScan and switched over to JPG 2000 structure by way of Kirtas applied sciences. All titles scanned disguise to hide and pages might comprise marks notations and different marginalia found in the unique quantity.

Ce cours de topologie a été dispensé en licence à l'Université de Rennes 1 de 1999 à 2002. Toutes les constructions permettant de parler de limite et de continuité sont d'abord dégagées, puis l'utilité de l. a. compacité pour ramener des problèmes de complexité infinie à l'étude d'un nombre fini de cas est explicitée.

PROJECTIVE INVARIANTS OF INTERSECTION OF CERTAIN PAIRS OF SURFACES CHUAN-CHIH HSIUNG 1. Introduction. In a recent paper [2] 1 the author has shown the existence, together with metric and projective characterizations, 2 of a unique projective invariant determined by the neighborhood of the second order of two surfaces Si, S2 at an ordinary point 0 in ordinary space when the tangent planes n, r 2 of the surfaces Si, 5 2 at the point 0 are distinct and the line / of intersection of the two tangent planes T\, T 2 does not coincide with any one of the asymptotic tangents of the surfaces Si, St at the point 0.
