On systems-disconjugacy and a question of Barrett
Published online by Cambridge University Press: 14 November 2011
Synopsis
In answer to a question raised by John Barrett in 1961, conditions are established under which the existence of a systems-conjugate point of a fourth-order equation also assures the existence of a 2–2 conjugate point. These results lead to new conjugacy criteria and apply to certain non-selfadjoint equations more general than those previously considered.
