Lie group structures on automorphism groups of real-analytic CR manifolds
- Publisher: The Johns Hopkins University Press
Pure & Applied Mathematics
Given any real-analytic CR manifold M, we provide general conditions on M guar-
anteeing that the group of all its global real-analytic CR automorphisms AutCR(M) is a Lie group
(in an appropriate topology). In particular, we obtain a Lie group structure for AutCR(M) when
M is an arbitrary compact real-analytic hypersurface embedded in some Stein manifold.
