摘要
We prove that if a holomorphic one-form Omega in a neighborhood of a closed euclidian ball B-2n subset of C-n, in the n-dimensional complex affine space, defines a distribution transverse to the boundary sphere S2n-1 = partial derivativeB(2n), then n is even and Omega admits a sole singularity q is an element of B-2n. Moreover, this singularity is simple. (C) 2004 Elsevier Ltd. All rights reserved.
