Abstract | |||||||||||||||
| this paper we consider the well-known Schur problem the solution of which satisfy in addition the extremal condition (z)w(z) min ; jzj < 1 (58.1) where w(z) and min are mxm matrices and min > 0 . Here the matrix min is de ned by a certain minimal-rank condition(see De nition 1).We remark that the extremal Schur problem is a particular case. The general case is considered in book [1] and paper [2].Our approach to the extremal problems doesn't coincide with the superoptimal approach [3],[4].In paper [2] we compare our approach to the extremal problems with the superoptimal approach | |||||||||||||||
