复正态过程存在的一个充要条件

A Sufficient and Necessary Condition of Existence of Complex Normal Process

通过系列分析,证明了复正态过程存在的充要条件为其协方差函数具有某种非负定性及对称性.所用的分析方法也与以往有所不同.

This paper proves the sufficient and necessary condition of existence of complex normal process is the that covariance functions have certain nonnegative definite property and symmetry, and the analytic methods are also different from the others.
