摘要
本文对文［１］的广义对角优势函数和文［４］的块严格对角占优函数概念进行了推广，提出了非线性广义块对角优势函数的概念，并对其性质，判别条件及应用进行了研究。获得了一些有意义的结果，这些结果推广和改进了文［１］与［４］的相应结果。
By generalizing generalized diagonally dominant functions and block strictly diagonally dominant functions ,we introduca concept of nonlinear generalized block diagonally dominant function and study their properties, criteria and application. Some results are obtained, and these results generalize and improve the corresponding results in and .
