Eigenvalue bounds for non-selfadjoint Dirac operators
We prove that the eigenvalues of the n-dimensional massive Dirac operator {mathscr {D}}_0 + V, nge 2, perturbed by a potential V, possibly non-Hermitian, are contained in the union of two disjoint disks of the complex plane, provided V is sufficiently small with respect to the mixed norms L^1_{x_j} L^infty _{{widehat{x}}_j}, for jin {1,dots ,n}.
