Subelliptic operators on weighted folland-stein spaces
BULLETIN OF THE INSTITUTE OF MATHEMATICS ACADEMIA SINICA NEW SERIES(2022)
Abstract
In this paper, we show that the sub-Laplacian of an asymptotically flat pseudo -Hermitian manifold defined on suitable weighted Folland-Stein spaces is an isomorphism. Similarly in dimension 5 a certain Dirac-type operator is shown to be an isomorphism, which is used to resolve the CR positive mass problem.
