| Abstract: | In this paper,we get optimal lower bounds for the eigenvalues of the Spin c Dirac-Witten operator.These estimates are given in terms of the mean curvature and different geometric invariants as the scalar curvature,the first eigenvalue of the perturbed Yamabe operator and the spinorial energy-momentum tensor.The limiting cases are also discussed. |
