Existence and asymptotics of eigenvalues of indefinite systems of Sturm-Liouville and Dirac type. (English) Zbl 0993.34024
Authors’ abstract: Existence and asymptotic behavior of eigenvalues of indefinite Sturm-Liouville and Dirac systems with integrable coefficients are investigated using Prüfer angle analysis. The results generalize those previously obtained by Atkinson, Mingarelli, Gohberg and Krein and are based on a new theorem that determines the asymptotic behavior of the solution to a Riccati-type equation containing a large parameter.
