A note on the example of J. Andres concerning the application of the Nielsen fixed-point theory to differential systems
This paper is concerned with the existence of positive solutions of a multi-point boundary value problem for higher-order differential equation with one-dimensional -Laplacian. Examples are presented to illustrate the main results. The result in this paper generalizes those in existing papers.
The paper is devoted to the question whether some kind of additional information makes it possible to determine the fundamental matrix of variational equations in . An application concerning computation of a derivative of a scalar Poincaré mapping is given.
We give a sufficient condition for the oscillation of linear homogeneous second order differential equation , where and is positive real number.
This paper deals with the oscillation problems on the nonlinear differential equation involving -Laplacian. Sufficient conditions are given under which all proper solutions are oscillatory. In addition, we give a-priori estimates for nonoscillatory solutions and propose an open problem.
