Eigenvalues behaviours for self-adjoint Pauli operators with unsigned   perturbations and admissible magnetic fields
  We investigate the behaviour of the eigenvalues of two-dimensional Pauli operators with nonconstant magnetic fields perturbed by a sign-indefinite decaying electric potential V. We prove new eigenvalues asymptotics.
