1. 基本的定义 正定和半正定这两个词的英文分别是positive definite和positive semi-definite,其中,definite是一个形容词,表示“明确的、确定的”等意思。 初学线性代数的读者可能会被这两个词“唬住”,但正定矩阵和半正定矩阵的定义实际上是很简单的 (不考虑复数构成的矩阵): 【定义1】给定一个大小为n×n的实...

The integral representation theorems for positive and negative definite functions obtained so far were all proved under the assumption that the semigroup contained a neutral element, i.e. a "zero" with respect to the additively written semigroup operation. We also saw that some boundedness ...
It is known that every complex square matrix with nonnegative determinant is the product of positive semi-definite matrices. There are characterizations of matrices that require two or five positive semi-definite matrices in the product. However, the characterizations of matrices that require three or...
