Non‐geometric rough paths on manifolds

J Armstrong, D Brigo, T Cass… - Journal of the London …, 2022 - Wiley Online Library
We provide a theory of manifold‐valued rough paths of bounded 3> p 3>p‐variation, which
we do not assume to be geometric. Rough paths are defined in charts, relying on the vector …

The parabolic Anderson model on Riemann surfaces

A Dahlqvist, J Diehl, BK Driver - Probability Theory and Related Fields, 2019 - Springer
We show well-posedness for the parabolic Anderson model on 2-dimensional closed
Riemannian manifolds. To this end we extend the notion of regularity structures to curved …

A new definition of rough paths on manifolds

Y Boutaib, T Lyons - Annales de la Faculté des sciences de Toulouse …, 2022 - numdam.org
Smooth manifolds are not the suitable context for trying to generalize the concept of rough
paths on a manifold. Indeed, when one is working with smooth maps instead of Lipschitz …

Chernoff approximations of Feller semigroups in Riemannian manifolds

S Mazzucchi, V Moretti, I Remizov… - Mathematische …, 2023 - Wiley Online Library
Chernoff approximations of Feller semigroups and the associated diffusion processes in
Riemannian manifolds are studied. The manifolds are assumed to be of bounded geometry …

Global existence of geometric rough flows

BK Driver - arXiv preprint arXiv:1810.03708, 2018 - arxiv.org
In this paper we consider rough differential equations on a smooth manifold $\left (M\right). $
The main result of this paper gives sufficient conditions on the driving vector-fields so that …
