位置对称的部分N-矩阵的完成问题

The Combinatorially Symmetric Partial N-matrix Completion

主要讨论了部分Toeplitz N-矩阵的完成问题及一类特殊结构的位置对称的部分N矩阵的完成.

An n-by-n matrix is called an N-matrix if all principal minors are negative. In this paper, we are interested in the partial Toeplitz N-matrix completion problem, and study rome eombinatorially symmetric partial N-matrix completion problem under certain conditions.
