Quenched path limits and periodization stability for tilted Brownian motion in Poissonian potentials on
Miklos Abert, Adam Arras, Jaelin Kim
We analyze the existence of Brownian motion tilted by a potential of full support on hyperbolic spaces . On compact spaces, it is classical that these path limits, ca…
The Uniform Random Walk on graphs, loop processes and graphings
Miklos Abert, Adam Arras, Jaelin Kim
We define the Uniform Random Walk (URW) on a connected, locally finite graph as the weak limit of the uniform walk of length starting at a fixed vertex. When the limit exists,…
Random Schrödinger operators and convolution on wreath products
Adam Arras
We establish a spectral correspondence between random Schrödinger operators and deterministic convolution operators on wreath products, generalizing previous results that relate La…
Existence of absolutely continuous spectrum for Galton-Watson random trees
Adam Arras, Charles Bordenave
We establish a quantitative criterion for an operator defined on a Galton-Watson random tree for having an absolutely continuous spectrum. For the adjacency operator, this criterio…
