Eigenvalue Comparison on Bakry-emery Manifolds
It is called shrinking, steady, or expanding soliton if a > 0, a = 0 or a < 0 respectively. More generally (M, g, f) is called a Bakry-Emery manifold if the so-called Bakry-Emery Ricci tensor Rcij + fij ≥ agij for some a ∈ R. In this paper we apply the modulus of continuity estimates developed in [AC,AC2,AC3] to give a different proof of an eigenvalue comparison estimate on Bakry-Emery manifold...
متن کاملGlobal Stabilization for Systems Evolving on Manifolds
We show that any globally asymptotically controllable system on any smooth manifold can be globally stabilized by a state feedback. Since we allow discontinuous feedbacks, we interpret the solutions of our systems in the “sample and hold” sense introduced by Clarke-Ledyaev-Sontag-Subbotin (CLSS). Our work generalizes the CLSS Theorem which is the special case of our result for systems on Euclid...
متن کاملOrders of Accumulation of Entropy on Manifolds
For a continuous self-map T of a compact metrizable space with finite topological entropy, the order of accumulation of entropy of T is a countable ordinal that arises in the theory of entropy structure and symbolic extensions. Given any compact manifold M and any countable ordinal α, we construct a continuous, surjective self-map of M having order of accumulation of entropy α. If the dimension...
متن کاملOptimization of the Lowest Eigenvalue for Leaky Star Graphs
We consider the problem of geometric optimization for the lowest eigenvalue of the two-dimensional Schrödinger operator with an attractive -interaction of a xed strength the support of which is a star graph with nitely many edges of an equal length L 2 (0;1]. Under the constraint of xed number of the edges and xed length of them, we prove that the lowest eigenvalue is maximized by the fully sym...
متن کاملStability Estimates for the Lowest Eigenvalue of a Schrödinger Operator
Abstract. There is a family of potentials that minimize the lowest eigenvalue of a Schrödinger eigenvalue under the constraint of a given L norm of the potential. We give effective estimates for the amount by which the eigenvalue increases when the potential is not one of these optimal potentials. Our results are analogous to those for the isoperimetric problem and the Sobolev inequality. We al...
