YU. R. HAKOPIAN, S.S. Aleksanyan · Proceedings of the YSU A Physical and Mathematical Sciences · 2016
The present paper is a direct continuation of the papers [1, 2]. We obtain intermediate results, which will be used in the next final fourth part of this study, where a definitive solution to the Moore–Penrose inversion problem for singular upper bidiagonal matrices is given.
