Xue Jiao, Chaoqian Li, Yaotang Li
Abstract
Some new sufficient conditions are given, which ensure that the k-subdirect sum of Nekrasov matrices and strictly diagonally dominant matrices is in the class of Nekrasov matrices. In addition, several examples are also given to illustrate the conditions presented.
