摘要

希尔伯特空间上的线性算子可以用有限矩阵逼近,方法是选择希尔伯特空间的一个正交基。本文用变分方法建立了有界和无界算子矩阵的数值范围的近似。给出了schringer算子、Stokes算子和Hain-LA μ st算子的应用。

Computing the q-Numerical Range of Differential Operators
A linear operator on a Hilbert space may be approximated with finite matrices by choosing an orthonormal basis of thez Hilbert space. In this paper, we establish an approximation of the - numerical range of bounded and unbounnded operator matrices by variational methods. Application to SchrA¶dinger operator, Stokes operator, and Hain-LA¼st operator is given.
