Oscillation of a forced higher order equation

Witold A. J. Kosmala (1994)

Annales Polonici Mathematici

Similarity:

We state and prove two oscillation results which deal with bounded solutions of a forced higher order differential equation. One proof involves the use of a nonlinear functional.

Oscillation of a logistic equation with delay and diffusion

Sheng Li Xie, Sui Sun Cheng (1995)

Annales Polonici Mathematici

Similarity:

This paper establishes oscillation theorems for a class of functional parabolic equations which arises from logistic population models with delays and diffusion.
