The well-known CLR-estimate for the number of negative eigenvalues of the Schrodinger operator \$-\Delta+V\$ is generalized to a class of second order magnetic operators, generalizing the magnetic Schrodinger operator. The cofficients in the magnetic operators are variable, they may be nonsmooth, unbounded and some degeneration is allowed.
Estimation of the number of negative eigenvalues of magnetic Schr\"odinger operators in a strip
An upper estimate for the number of negative eigenvalues below the essential spectrum for the magnetic Schrödinger operator with Aharonov-Bohm magnetic field in a strip is obtained. Its further shown
