In mathematics, especially several complex variables, an analytic polyhedron is a subset of the complex space of the form
where is a bounded connected open subset of and are holomorphic on D.[1] If above are polynomials, then the set is called a polynomial polyhedron. Every analytic polyhedron is a domain of holomorphy (thus, pseudo-convex.)
The boundary of an analytic polyhedron is the union of the set of hypersurfaces
An analytic polyhedron is a Weil polyhedron, or Weil domain if the intersection of hypersurfaces has dimension no greater than .[2]
See also: the Behnke–Stein theorem.
