非Hermite算子特征向量构成的双正交基的存在性

On Existence of a Biorthonormal Basis Composed of Eigenvectors of Non-Hermitian Operators

Toshiaki Tanaka

摘要:

本文给出了非厄米特算子的特征向量构成的双正交基存在的一组必要条件。作为一个例子,我们研究这些条件的情况下,正常的运营商。我们还提供了一个推广的条件,这是适用于非对角化的运营商,不仅考虑本征向量,而且所有的根向量。

英文摘要:

We present a set of necessary conditions for the existence of a biorthonormal basis composed of eigenvectors of non-Hermitian operators. As an illustration, we examine these conditions in the case of normal operators. We also provide a generalization of the conditions which is applicable to non-diagonalizable operators by considering not only eigenvectors but also all root vectors.
