3 Scopus citations


We consider the space, CRp(M), consisting of CR functions which also lie in Lp(M) on a quadric submanifold M of Cn of codimension at least one. For 1 ≤ p ≤ ∞, we prove that each element in CRp(M) extends uniquely to an Hp function on the interior of the convex hull of M. As part of the proof, we establish a semi-global version of the CR approximation theorem of Baouendi and Treves for submanifolds which are graphs and whose graphing functions have polynomial growth.
