Spectral theory of ordinary differential operators. (English) Zbl 0647.47052
Lecture Notes in Mathematics, 1258. Berlin etc.: Springer-Verlag. VI, 303 p.; DM 50.00 (1987).
The author’s intention is to provide a general and rather complete theory of self-adjoint ordinary differential operators of arbitrary order n operating on \({\mathbb{C}}^ m\)-valued functions, m being an arbitrary natural number; and to apply this theory to Sturm-Liouville operators and Dirac systems, paying special attention to oscillation theory and absolute continuity of the spectrum. He has succeeded in producing an attractive, compact volume which is virtually self-contained and should be of considerable interest to the large number of mathematicians with interests in spectral theory ans.
