摘要

在本文中，我们刻画了Moore-Penrose逆为三对角的奇异三对角m矩阵，扩展了最近（Barreras and Peña, 2019）描述逆为三对角的非奇异三对角m矩阵的结果。

Tridiagonal M-matrices with tridiagonal Moore-Penrose inverse

In this paper, we characterize the singular tridiagonal M-matrices whose Moore-Penrose inverse is tridiagonal, extending the recent result (Barreras and Peña, 2019) describing the nonsingular tridiagonal M-matrices whose inverse is tridiagonal.

期刊介绍： Applied Mathematics and Computation addresses work at the interface between applied mathematics, numerical computation, and applications of systems – oriented ideas to the physical, biological, social, and behavioral sciences, and emphasizes papers of a computational nature focusing on new algorithms, their analysis and numerical results. In addition to presenting research papers, Applied Mathematics and Computation publishes review articles and single–topics issues.
