RESEARCH INTERESTS AND CURRENT RESEARCH WORKS
LOWER BOUNDS FOR EIGENVALUES OF THE DIRAC-Witten OPERATOR.    
We get optimal lower bounds for the eigenvalues of the Dirac-Witten operator of  compact (with or without boundary) spin spacelike hypersurfaces of a Lorentian manifold in terms of the mean curvature and the scalar curvature and the energy-momentum tensor. In the limiting case, we find the spacelike hypersurface has constant Ricci curvature and mean curvature.    
Currently, we are doing some research on foliations and related vanishing theorems.
