Purkyně University, Janáčkovo náměstí 2a, 662 95 Brno, Czechoslovakia Existence of conjugate points for self-adjoint linear differential equations [Elektronische Daten] [Ondřej Došlý] The conjecture of Muller-Pfeiffer [4] concerning the oscillation behaviour of the differential equation (-l)n(p(x)y(n))(n) + q(x)y = 0 is proved, and a similar conjecture concerning the more general differential equation ∑nk=0(−l)k(Pk(x)y(k)(k + q(x)y= 0 is formulated.
