Small eigenvalues of the Witten Laplacian with Dirichlet boundary conditions: the case with critical points on the boundary

Dorian Le Peutrec and Boris Nectoux

Vol. 14 (2021), No. 8, 2595–2651
Abstract

We give sharp asymptotic equivalents in the limit h 0 of the small eigenvalues of the Witten Laplacian, that is, the operator associated with the quadratic form

ψ H01(Ω)h2Ω|(e1 hfψ)|2e2 hf,

where Ω ¯ = Ω Ω is an oriented C compact and connected Riemannian manifold with nonempty boundary Ω and f : Ω ¯ is a C Morse function. The function f is allowed to admit critical points on Ω, which is the main novelty of this work in comparison with the existing literature.
