Über einige Randwertprobleme dritter Ordnung
Two sorts of nonlinear third order boundary-value problems are solved and the existence of eigenvalues and eigenfunctions is proved.
In this paper we will study some asymptotic properties of a nonlinear third order differential equation viewed as a perturbation of a simpler nonlinear equation investigated recently by the authors in [4].
In this paper we shall study some oscillatory and nonoscillatory properties of solutions of a nonlinear third order differential equation, using the results and methods of the linear differential equation of the third order.
Sufficient conditions for oscillation of a certain nonlinear trinomial third order differential equation are proved.
In this paper a singular third order eigenvalue problem is studied. The results of the paper complete the results given in the papers [3], [5].
