Euclidean geometry — A Greek mathematician performing a geometric construction with a compass, from The School of Athens by Raphael. Euclidean geometry is a mathematical system attributed to the Alexandrian Greek mathematician Euclid, which he described in his… … Wikipedia
Semi-anneau d'ensembles — Ne doit pas être confondu avec semi anneau. Un semi anneau d ensembles (généralement abrégé en semi anneau) est une classe de parties d un ensemble X à partir de laquelle on construit facilement un anneau d ensembles. C est un cadre commode … Wikipédia en Français
Semi-locally simply connected — In mathematics, in particular topology, a topological space X is called semi locally simply connected if every point x in X has a neighborhood U such that the homomorphism from the fundamental group of U to the fundamental group of X , induced by … Wikipedia
