Abstract :
The mapping of the polyhedron of coefficients of a polynomial into the root plane is considered. An angle of the sector (depending on the dimension of the polyhedron) is determined, in which the domains of roots are bounded by disjoint images of the edges. The coordinates of the edge route, which is mapped on the boundaries of the root domains in the sector, are found. Some conditions of the robust sector stability of an interval polynomial are formulated
