Pa. Binding et H. Volkmer, Existence and asymptotics of eigenvalues of indefinite systems of Sturm-Liouville and Dirac type, J DIFF EQUA, 172(1), 2001, pp. 116-133
Existence and asymptotic behavior of eigenvalues of indefinite Sturm-Liouvi
lle and Dirac systems with integrable coefficients art investigated using P
rufer angle analysis. The results generalize those previously obtained by A
tkinson, Mingarelli. Gohberg and Krein and are based on a new theorem that
determines tile asymptotic behavior of the solution of a Riccati-type equat
ion containing a large parameter. (C) 2001 Academic Press
