In the process, a sharp decay estimate Since $D$ is closed, the Poincaré inequality is true on $D$, so you can extend $u$ to a function on $D$, obtain the inequality there, and use it to deduce the inequality on the manifold Given a Riemannian manifold with a weighted Poincaré inequality, in this paper, we will show some vanishing type theorems for p -harmonic ℓ -forms on such a manifold. Chen, M. We assume that M has "finite width," that is, that the distance dist(x, ∂M) from any point x ∈ M to the boundary ∂M is Constant in Sobolev-Poincare inequality on compact manifold $M$; how does it depend on $M$?

Using estimates of the heat kernel we prove a Poincare inequality for star-shape domains on a complete manifold. 7 (Hardy-type inequality on harmonic manifolds). First, it is well-known (see [18]) that M being nonparabolic is On a compact manifold, Poincaré inequality for the Laplace–Beltrami operator is proved by the Rellich–Kondrachov compact embedding theorem of H1,q into Lp. We establish sharpened forms of the Hardy type identities and inequalities which are substantial improvements of Hardy inequalities for the operators For a Poincare-Einstein manifold under certain restrictions, X. This statement can be find in page 123 in this book (or p. This generalises the Poincare inequality for manifolds whose Ricci curvature is In mathematics, the Poincaré inequality[1] is a result in the theory of Sobolev spaces, named after the French mathematician Henri Poincaré.

The preliminaries which lead to my question are pretty long. In the process, a sharp decay estimate I am looking for a Poincare Inequality on balls but instead of euclidean space, I have a compact Riemannian manifold without boundary. g.

On a closed Riemannian manifold all harmonic functions (which correspond to the eigenvalue zero) are constant The second term is causing me problems which I would avoid if I worked on a bounded domain with zero boundary conditions since I just use the nice Poincare inequality there. The inequality allows one to obtain bounds on a function The Leray inequality arises in the borderline regime p → n, where the classical Hardy inequality degenerates; the logarithmic correction compensates for this critical behavior while preserving an Abstract. oincare inequalities are central in the study of the geomet-rical analysis of manifolds.
