Analytic Polyhedron
In mathematics, especially several complex variables, an analytic polyhedron is a subset of the complex space of the form :P = \ where is a bounded connected open subset of , f_j are holomorphic on and is assumed to be relatively compact in .See and . If f_j above are polynomials, then the set is called a polynomial polyhedron. Every analytic polyhedron is a domain of holomorphy and it is thus pseudo-convex. The boundary of an analytic polyhedron is contained in the union of the set of hypersurfaces : \sigma_j = \, \; 1 \le j \le N. An analytic polyhedron is a ''Weil polyhedron'', or Weil domain if the intersection of any of the above hypersurfaces has dimension no greater than ..

It was proved by ... * Be ...

Mathematics
Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics with the major subdisciplines of number theory, algebra, geometry, and analysis, respectively. There is no general consensus among mathematicians about a common definition for their academic discipline. Most mathematical activity involves the discovery of properties of abstract objects and the use of pure reason to prove them. These objects consist of either abstractions from nature orin modern mathematicsentities that are stipulated to have certain properties, called axioms. A ''proof'' consists of a succession of applications of deductive rules to already established results. These results include previously proved theorems, axioms, andin case of abstraction from naturesome basic properties that are considered true starting poin ...
