M(\(\lambda\) ) theory for singular Hamiltonian systems with two singular points. (English) Zbl 0694.34013

The present work is a continuation of an earlier work of the author [ibid. 20, No.3, 664-700 (1989; Zbl 0683.34008)]. In this work, the 2m- dimensional Hamiltonian system \(JY'=(\lambda A+B)Y\) on an interval (a,b) is considered, where both a and b are singular points. A Green’s function is derived using separated singular boundary conditions and it is used to show that the singular boundary value problem consisting of the differential equation and boundary conditions is self-adjoint. A doubly singular version of Green’s formula is derived and all self-adjoint boundary value problems arising from the differential equation are characterized.
