Abstract
Let M be a generic CR submanifold in , m = CR dim M ≥ 1, n = codim M ≥ 1, d = dim M = 2m + n. A CR meromorphic mapping (in the sense of Harvey-Lawson) is a triple , where: 1) is a ¹-smooth mapping defined over a dense open subset of M with values in a projective manifold Y; 2) the closure of its graph in defines an oriented scarred ¹-smooth CR manifold of CR dimension m (i.e. CR outside a closed thin set) and 3) in the sense of currents. We prove that extends meromorphically to a wedge attached to M if M is everywhere minimal and (real-analytic) or if M is a globally minimal hypersurface.
Keywords
CR generic currents, scarred CR manifolds, removable singularities for CR functions, deformations of analytic discs, CR meromorphic mappings
