Gaussian Upper Bounds for the Heat Kernel on Arbitrary Manifolds
نویسنده
چکیده
The history of the heat kernel Gaussian estimates started with the works of Nash [25] and Aronson [2] where the double-sided Gaussian estimates were obtained for the heat kernel of a uniformly parabolic equation in IR in a divergence form (see also [15] for improvement of the original Nash’s argument and [26] for a consistent account of the Aronson’s results and related topics). In particular, the Aronson’s upper bound for the case of time-independent coefficients which is of interest for us reads as follows:

Heat kernel bounds, Poincaré series, and L spectrum for locally symmetric spaces
We derive upper Gaussian bounds for the heat kernel on complete, non-compact locally symmetric spaces M = Γ\X with non-positive curvature. Our bounds contain the Poincaré series of the discrete group Γ and therefore we also provide upper bounds for this series.
متن کاملHeat kernels on manifolds, graphs and fractals
We consider heat kernels on different spaces such as Riemannian manifolds, graphs, and abstract metric measure spaces including fractals. The talk is an overview of the relationships between the heat kernel upper and lower bounds and the geometric properties of the underlying space. As an application some estimate of higher eigenvalues of the Dirichlet problem is considered.
متن کاملRobust Distributed Source Coding with Arbitrary Number of Encoders and Practical Code Design Technique
The robustness property can be added to DSC system at the expense of reducing performance, i.e., increasing the sum-rate. The aim of designing robust DSC schemes is to trade off between system robustness and compression efficiency. In this paper, after deriving an inner bound on the rate–distortion region for the quadratic Gaussian MDC based RDSC system with two encoders, the structure of...
متن کاملBounds on the heat kernel of the Schrödinger operator in a random electromagnetic field
We obtain lower and upper bounds on the heat kernel and Green functions of the Schrödinger operator in a random Gaussian magnetic field and a fixed scalar potential. We apply stochastic Feynman-Kac representation, diamagnetic upper bounds and the Jensen inequality for the lower bound. We show that if the covariance of the electromagnetic (vector) potential is increasing at large distances then ...
متن کاملUpper Bounds for the Spectral Function on Homogeneous Spaces via Volume Growth
We use the so-called spectral embedding to give upper bounds on the spectral function of the Laplace-Beltrami operator on homogeneous spaces in terms of the volume growth of balls. In the case of compact manifolds, our bounds extend the 1980 lower bound of Peter Li [Li80] for the smallest positive eigenvalue to all eigenvalues. We also improve Li’s bound itself. Our bounds translate to explicit...
