Spectral gap estimates for Brownian motion on domains with sticky-reflecting boundary diffusion
Vitalii Konarovskyi, Victor Marx, Max von Renesse
Introducing an interpolation method we derive lower bounds for the spectral gap for Brownian motion on general domains with sticky-reflecting boundary diffusion associated to the f…
On Conditioning Brownian Particles to Coalesce
Vitalii Konarovskyi, Victor Marx
We introduce the notion of a conditional distribution to a zero-probability event in a given direction of approximation, and prove that the conditional distribution of a family of…
A Bismut-Elworthy inequality for a Wasserstein diffusion on the circle
Victor Marx
We introduce in this paper a strategy to prove gradient estimates for some infinite-dimensional diffusions on -Wasserstein spaces. For a specific example of a diffusion on the…
Infinite-dimensional regularization of McKean-Vlasov equation with a Wasserstein diffusion
Victor Marx
Much effort has been spent in recent years on restoring uniqueness of McKean-Vlasov SDEs with non-smooth coefficients. As a typical instance, the velocity field is assumed to be bo…
A new approach for the construction of a Wasserstein diffusion
Victor Marx
We propose in this paper a construction of a diffusion process on the Wasserstein space P\_2(R) of probability measures with a second-order moment. This process was introduced in s…
