Geometric rough paths on infinite dimensional spaces
(Peer reviewed; Journal article, 2022)Similar to ordinary differential equations, rough paths and rough differential equations can be formulated in a Banach space setting. For α ∈ (1/3,1/2), we give criteria for when we can approximate Banach space-valued ... -
Lie theory for asymptotic symmetries in general relativity : The BMS group
(Peer reviewed; Journal article, 2022)We study the Lie group structure of asymptotic symmetry groups in General Relativity from the viewpoint of infinite-dimensional geometry. To this end, we review the geometric definition of asymptotic simplicity and emptiness ...
