Abstract
Classical H. Minkowski theorems on existence and uniqueness of con-
vex polyhedra with prescribed directions and areas of faces as well as the
well-known generalization of H. Minkowski uniqueness theorem due to
A. D. Alexandrov are extended to a class of nonconvex polyhedra which
are called polyhedral herissons and may be described as polyhedra with
injective spherical image.
Key words: convex polyhedron, polyhedral surface, polyhedral hedge-
hog, equipment, virtual polytope, polygon, Cauchy lemma, open mapping.
