dc.description.abstractEn | We study the spectrum of the semiclassical Witten Laplacian associated to a smooth function f. We assume that f is a confining Morse-Bott function. Under this assumption we show that the Witten Laplacian admits exponentially small eigenvalues separated from the rest of the spectrum. Moreover, we establish Eyring-Kramers formula for these eigenvalues. Our approach is based on microlocal constructions of quasimodes near the critical submanifolds. | |
