Abstract:
The article deals with the multidimensional discrete analogue of the Minkowski problem in the production of A. D. Aleksandrov on the existence of a convex polyhedron with given curvatures at the vertices. We find the conditions for the solvability of this problem in a general setting, when the curvature measure at the polyhedron vertices is defined by an arbitrary continuous function defined on a field $F: \mathbb S^{n-1}\to (0,+\infty)$. The basis for solving the problem is the solvability of the problem whether each triangulation of a finite set of points $ P \subset \mathbb S^{n-1} $ of the unit sphere corresponds a convex polyhedron whose faces normal belong to the set $ P $.
Key words:
convex polyhedron, triangulation, spherical simplex.
