Abstract

Let ZCNZ\subset\mathbb{C}^N be an nn-pseudoconcave subset, for 1n<N1\leq n<N, which is locally the graph of a continuous function over a closed subset of Cn×R\mathbb{C}^n\times\mathbb{R}. We show that ZZ can be realised as the disjoint union of nn-dimensional complex manifolds. In particular, the same conclusion can be made for any nn-pseudoconcave subset ZZ of the graph Γ(g)\Gamma(g) of a continuous function g:DCn×RR×Cpg:D\subset\mathbb{C}^n\times\mathbb{R}\to\mathbb{R}\times\mathbb{C}^p, for n1n\geq 1 and p0p\geq 0.
