## Abstract We consider families of generalized Dirac operators __D__~__t__~ with constant principal symbol and constant essential spectrum such that the endpoints are gauge equivalent, i.e., __D__~1~ = __W__\*__D__~0~__W__. The spectral flow un any gap in the essential spectrum we express as the F

On a foliated Riemannian manifold with a Kรคhler spin foliation, we give a lower bound for the square of the eigenvalues of the transversal Dirac operator. We prove, in the limiting case, that the foliation is a minimal, transversally Einsteinian of odd complex dimension with nonnegative constant tra
