Théorie des Opérateurs et la décomposition en valeurs singulières

Cet instantané concerne la théorie des opérateurs et un de ses outils fondamentaux : la décomposition en valeur singulières (ou SVD, de l’anglais « Singular Value Decomposition »). La SVD factorise les applications linéaires en applications plus simples et dévoile leurs propriétés géométriques. De par sa capacité à organiser l’information, cet outil est devenu important dans de nombreux domaines des mathématiques appliquées. Nous traitons ici de la DVS dans les cas concrets de transformations linéaires dans le plan (telles que la rotation ou la réflexion).
