However it fails in the large, as has been shown by the counterexample found in [HN1]. Hence there is an underlying obstruction to the global H-principle on a pseudoconcave CR manifold. The purpose of this note is to take the first steps toward a deeper understanding of this obstruction.Complex VariablesAnalysis of PDEsAlgebraic Topology32V10; 32V25; 32D20text
