This work studies the local well-posedness of the initial-value problem for the nonlinear sixth-order Boussinesq equation utt = uxx + uxxxx + uxxxxxx + (u2)xx, where = ±1. We prove local well-posed...
In this note, we prove the conjecture of Payne and Schaefer [2], regarding an overdetermined boundary value problem for the triharmonic operator, Δ3 = ΔΔΔ. It is deduced that if a solution of the prob...
In this paper we extend the oscillation criteria of impulsive hyperbolic equations with neutral type for sixth-order case in [3].
Differential transformation method is applied to construct semi numericalanalytic solutions of linear sixth-order boundary value problems with two-point boundary value conditions. Two examples are con...
