摘要

We study semi-classical eigenvalues of a Schr?dinger operator with delta-potential on 2D or 3D symmetric manifold. We describe Lagrangian manifolds, corresponding to such eigenvalues and compute the asymptotics of eigenvalues for different values of the parameter, defining the operator. We describe also the effect of the jump of the Maslov index while passing through the critical value of this parameter. These results were obtained in a number of joint papers with T. Filatova, T. Ratiu and A. Suleimanova.
