We derive a Reilly-type formula for differential p-forms on a compact manifold with boundary and apply it to give a sharp lower bound of the spectrum of the Hodge Laplacian acting on differential forms of an embedded hypersurface of a Riemannian manifold. The equality case of our inequality gives rise to a number of rigidity results, when the geometry of the boundary has special properties and the domain is non-negatively curved. Finally, we also obtain, as a byproduct of our calculations, an… 
On convex hypersurfaces in space forms and eigenvalue estimates for differential forms
We apply Reilly's formula and Hsiung-Minkowski formulas to obtain some geometric and analytic results. In the first part, we obtain some sharp integral inequalities on a convex hypersurface in space

Rigidity results for spin manifolds with foliated boundary
In this paper, we consider a compact Riemannian manifold whose boundary is endowed with a Riemannian flow. Under a suitable curvature assumption depending on the O’Neill tensor of the flow, we prove
The Bochner formula for isometric immersions
We study the Bochner formula for a manifold isometrically immersed into another and obtain a Gauss-type splitting of its curvature term. In fact, we prove that the curvature term in the Bochner

AbstractOn a compact Riemannian manifold N whose boundary is endowed with a Riemannian flow, we gave in El Chami et al. (Eigenvalue estimate for the basic Laplacian on manifolds with foliated
The smooth Riemannian extension problem
Given a metrically complete Riemannian manifold $(M,g)$ with smooth nonempty boundary and assuming that one of its curvatures is subject to a certain bound, we address the problem of whether it is

Eigenvalue and gap estimates for the Laplacian acting on p-forms
We study the gap of the first eigenvalue of the Hodge Laplacian acting on p-differential forms of a manifold with boundary, for consecutive values of the degree p. We first show that the gap may assume
Rigidity of compact manifolds with boundary and nonnegative Ricci curvature
Let Ω be an (n + 1)-dimensional compact Riemannian manifold with nonnegative Ricci curvature and nonempty boundary M = ∂Ω. Assume that the principal curvatures of M are bounded from below by a
Dirac Operator on Embedded Hypersurfaces
New extrinsic lower bounds are given for the classical Dirac operator on the boundary of a compact domain of a spin manifold. The main tool is to solve some boundary problems for the Dirac operator
Totally umbilical hypersurfaces of a locally product Riemannian manifold
It is well known that a totally umbilical hypersurface withnon-vanishing mean curvature of a Euclidean space is isometric with a sphere. Toprove this theorem we use, among others, the fact that in a

Abstract. Under intrinsic and extrinsic curvature assumptions on a Riemannian spin manifold and its boundary, we show that there is an isomorphism between the restriction to the boundary of parallel
