In this contribution we investigate oscillation and spectral properties of self-adjoint differential operators of the form r~ M(y ## ' + L~o~(I). where t C I := [a, co), r~ > 0 and r0 .... ,m-l, 77 Oscillation and nonoscillation of (1.1) are defined using the concept of conjugate points. Two
We consider not necessarily self-adjoint differential operators generated by ordinary differential expressions of the form My= f: pi(t)y"' on Z=[l, co) (\*) i=O with n = ord(M) E N, pi E ci(Z, C). With A4 + we denote the adjoint expression b!f+y= i (-l)Qi(t)y)(i) i=O and with 7',(M) and T,(M) the mi
