摘要
本文基于分块算子技术与算子谱理论,建立了两个正交投影的交织算子与直接旋转的一般显式表达式。因此,它改进了 Kato 的结果(Perturbation Theory of Linear operators, Springer-Verlag, Berlin/Heidelberg, 1996);J. Avron, R. Seiler 和 B. Simon 的定理 2.3(The index of a pair of projections, J. Funct. Anal. 120(1994) 220-237)以及 C. Davis, W.M. Kahan 的结果(The rotation of eigenvectors by a perturbation, III. SIAM J. Numer. Anal. 7(1970) 1-46)。
