Heat Kernel Upper Bounds on Long Range Percolation Clusters
In this paper, we derive upper bounds for the heat kernel of the simple random walk on the infinite cluster of a supercritical long range percolation process. For any d ≥ 1 and for any exponent s ∈ (d, (d + 2) ∧ 2d) giving the rate of decay of the percolation process, we show that the return probability decays like t− /s−d up to logarithmic corrections, where t denotes the time the walk is run....
متن کاملGaussian Upper Bounds for the Heat Kernel on Arbitrary Manifolds
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, ...
متن کاملBuilding of Heat Kernel on Non-Compact Homogeneous Spaces
Method of the solution of the main problem of homogeneous spaces thermodynamics on non-compact spaces in the case of non-compact homogeneous spaces is presented in the article. The method is based on the formalism of coadjoint orbits. In that article we present algorithm that allows e ciently evaluate heat kernel on non-compact homogeneous spaces. The method is illustrated with non-trivial exam...
متن کاملHeat Kernel Upper Bounds for Interacting Particle Systems
We show a diffusive upper bound on the transition probability of a tagged particle in the symmetric simple exclusion process. The proof relies on optimal spectral gap estimates for the dynamics in finite volume, which are of independent interest. We also show off-diagonal estimates of Carne-Varopoulos type.

متن کاملKernel: Lower and Upper Bounds
Through this lecture note we try to provide a portal into the emerging filed of kernelization. We exhibit through examples various tools to prove both lower and upper bounds on the kernel sizes.
