On Open Problems of Nonnegative Inverse Eigenvalues Problem
Author(s) Jun-Liang Wu
ABSTRACT
In this paper, we give solvability conditions for three open problems of nonnegative inverse eigenvalues problem (NIEP) which were left hanging in the air up to seventy years. It will offer effective ways to judge an NIEP whether is solvable.
