Two scale analysis of a bounded family in \(L^2\) on a submanifold of the phase space. (Analyse à deux échelles d’une suite bornée de \(L^2\) sur une sous-variété du cotangent.) (French. Abridged English version) Zbl 1067.35083

Summary: We investigate the generalization of two-scale Wigner measure to the case of submanifolds more general than symplectic and involutive ones for which they have been defined. We study the concentration of a bounded family in \(L^2(\mathbb R^d)\) on a submanifold of the cotangent space \(T^{\ast}\mathbb R^d\) for which the restriction of the symplectic form to its tangent space is of constant rank.
