We prove that the number of negative eigenvalues of two-dimensional magnetic Schroedinger operators is bounded from above by the strength of the corresponding electric potential. Such estimates fail in the absence of a magnetic field. We also show how the corresponding upper bounds depend on the properties of the magnetic field and discuss their connection with Hardy-type inequalities. 
Estimation of the number of negative eigenvalues of magnetic Schr\"odinger operators in a strip

An upper bound on the number of eigenvalues of H smaller than any positive value is obtained, which involves the minimum of B and the square of the L^2 -norm of A( r)/r, where A(r) is the specific magnetic potential defined as the flux of the magnetic field through the disk of radius r centerde in the origin.
Estimates for the number of eigenvalues of two dimensional Schrödinger operators lying below the essential spectrum

We prove that the inclusion of a non-trivial magnetic field into a critical Schrodinger operator always removes the criticality and implies a corresponding Hardy type inequality.
