Estimations pour le nombre de valeurs propres négatives de l’opérateur de Schrödinger avec potentiels singuliers. (Estimates for the number of negative eigenvalues of the Schrödinger operator with singular potentials). (French) Zbl 0611.35064

The estimates from above and from below for a number of the negative eigenvalues of the Schrödinger operator with singular potentials in a domain \(X\subset {\mathbb{R}}^ d\) (d\(\geq 3)\) with the Dirichlet boundary condition is given. These estimates are highly uniform and imply precise eigenvalue asymptotics in a number of cases when operator depends on parameters.
