摘要
讨论复变实值函数复Hessian矩阵的性质,获得一些新的结果,并给出复Hessian矩阵复(半)正定性与Hermite(半)正定性的一些充要条件。
The properties of the complex Hessian matrices of real-valued functions with respect to a complex-valued vector variable are discussed and some new results are gained. In addition,several necessary and sufficient conditions of the complex positive (semi)definite and Hermitian positive (semi)definite of the complex Hessian matrices are established.
