Given two self-adjoint operators A and V = V + -V -, we study the motion of the eigenvalues of the operator A t = A -tV as t increases. Let α > 0 and let λ be a regular point for A. We consider the quantities N + V λ α , N -V λ α , and N 0 V λ α defined as the number of eigenvalues of the operator A
