Geometric Conditions for the Recovery of Sparse Signals on Graphs from Measurements Generated with Heat Kernels
… of the signal smoothed by evolving it under the heat equation governed by the graph Laplacian. The results discussed here are in close analogy to the mathematical theory of super-resolution developed by Cand`es and Fernandez-Granda for finitely supported measures on Euclidean spaces. As in the …

Heat trace and heat content asymptotics for Schrodinger Operators of stable processes/fractional Laplacians
… ↓ 0. These quantities are called the <em>heat trace</em> and <em>heat content</em> in <strong>R</strong><em><sup>d</sup></em> with respect to <em>V</em>, respectively. Here, <em>p</em>((α)/<em> t</em>)(<em>x, y</em>) and <em>p</em>(<em><sup> H<sub>V</sub></sup></em>/<em>t</em>)(<em>x, …

Homogenization of Random Media: Random Walks, Diffusions and Stochastic Interface Models
… results, in particular scaling limits and heat kernel estimates, for random processes moving in random environments and for stochastic interface models. The first chapter will survey recent research and introduce three models of interest: the random conductance model, the Ginzburg-Landau ∇φ …
