Abstract
In this paper, based on the block operator technique and operator spectral theory, general explicit descriptions for intertwining operators and direct rotations of two orthogonal projections are established. As a consequence, Kato's result (Kato, 1996 [14]) is improved, so are J. Avron, R. Seiler and B. Simon's Theorem 2.3 (Avron et al., 1994 [6]) and C. Davis, W.M. Kahan's result (Davis and Kahan, 1970 [11]).
