Abstract

Let MM be a generic CR submanifold in \Cm+n\C^{m+n}, m=CRdimM1m= CRdim M \geq 1,n=codimM1n=codim M \geq 1, d=dimM=2m+nd=dim M = 2m+n. A CR meromorphic mapping (in the sense of Harvey-Lawson) is a triple (f,Df,[Γf])(f,{\cal D}_f, [\Gamma_f]), where: 1. f:DfYf: {\cal D}_f \to Y is a C1{\cal C}^1-smooth mapping defined over a dense open subset Df{\cal D}_f of MM with values in a projective manifold YY; 2. The closure Γf\Gamma_f of its graph in \Cm+n×Y\C^{m+n} \times Y defines a oriented scarred C1{\cal C}^1-smooth CR manifold of CR dimension mm (i.e. CR outside a closed thin set) and 3. Such that d[Γf]=0d[\Gamma_f]=0 in the sense of currents. We prove in this paper that (f,Df,[Γf])(f,{\cal D}_f, [\Gamma_f]) extends meromorphically to a wedge attached to MM if MM is everywhere minimal and Cω{\cal C}^{\omega} (real analytic) or if MM is a C2,α{\cal C}^{2,\alpha} globally minimal hypersurface.
