Positive solutions of a nonlinear algebraic system with sign-changing coefficient matrix
Abstract Existence of positive solutions for the nonlinear algebraic system x = λ G F ( x ) $x=\lambda GF ( x ) $ has been extensively studied when the n × n $n\times n$ coefficient matrix G is positive or nonnegative. However, to the best of our knowledge, few results have been obtained when the co...
