W空间中有界线性算子的最佳逼近及其应用

Convolution and bounded operator

卷积与算子的有界性

Let k ∈ C ( R++) and B be a linear bounded operator.

设k∈C（R+）和B是一个有界线性算子。

For a linear bounded operator in finite dimensional Hilbert space, we first introduce the definition of exactly positive and give a sufficient and necessary condition by the way of space decomposition of the operator;

对有限维Hilbert空间的线性算子，引入了恰好正的概念，并利用算子的空间分解，得到了其存在惟一正逼近的充分必要条件；

In this paper a new linear, continuous and bounded operator& piecewise general orthogonal polynomials operator ( PGOPO) is proposed, and its main properties and operational rules are described.

提出了一类新型的线性、有界算子&分段广义正交多项式算子（PGOPO），建立了其主要性质及运算规则；

We discuss the best generalized inverse of linear bounded operator in finite dimension Hilbert space. We proved Moore-Penrose generalized inverse is the best generalized inverse.

本文讨论了有限维Hilbert空间中有界线性算子的最佳广义逆问题，证明了Moore-Penrose广义逆为最佳的。
