The first biharmonic Steklov eigenvalue: positivity preserving and shape optimization

We consider the Steklov problem for the linear biharmonic equation. We survey existing results for the positivity preserving property to hold. These are connected with the first Steklov eigenvalue. We address the problem of minimizing this eigenvalue among suitable classes of domains. We prove the existence of an optimal convex domain of fixed measure. Mathematics Subject Classification (2000)....

On the First Eigenvalue of a Fourth Order Steklov Problem

We prove some results about the first Steklov eigenvalue d1 of the biharmonic operator in bounded domains. Firstly, we show that Fichera’s principle of duality [9] may be extended to a wide class of nonsmooth domains. Next, we study the optimization of d1 for varying domains: we disprove a long-standing conjecture, we show some new and unexpected features and we suggest some challenging problem...

Evolution of the first eigenvalue of buckling problem on Riemannian manifold under Ricci flow

Among the eigenvalue problems of the Laplacian, the biharmonic operator eigenvalue problems are interesting projects because these problems root in physics and geometric analysis. The buckling problem is one of the most important problems in physics, and many studies have been done by the researchers about the solution and the estimate of its eigenvalue. In this paper, first, we obtain the evol...

A Global Curvature Pinching Result of the First Eigenvalue of the Laplacian on Riemannian Manifolds

and Applied Analysis 3 then there exists a constant C 3 (n) > 0 such that λ 1 (M) ≥ C 3 (n). Proof. The proof mainly belongs to Li and Yau [6]. Let u be the normalized eigenfunction ofM, set V = log (a + u) where a > 1. Then, we can easily get that ΔV = −λ 1 (M) u a + u − |∇V| 2 . (8) Denote that Q(x) = |∇V|(x), and we then have by the Ricci identity on manifolds with Ric (M) ≥ 0:

A Geometry Preserving Kernel over Riemannian Manifolds

Abstract- Kernel trick and projection to tangent spaces are two choices for linearizing the data points lying on Riemannian manifolds. These approaches are used to provide the prerequisites for applying standard machine learning methods on Riemannian manifolds. Classical kernels implicitly project data to high dimensional feature space without considering the intrinsic geometry of data points. ...
