Ping Fang, Zhou Yu-zhong, Xin Zhang · 2010
In this paper, we clearly study the properties of the Hermite positive definite solutions of a nonlinear matrix equation and improve a result. We get that if a condition is satisfied, all eigenvalues of the Hermite positive definite solutions of the equation locate in a range.
