The solution to a differential equation is called oscillatory if its set of zeros is unbounded. This does not necessarily mean that the solution is periodic, but that it crosses the horizontal axis infinitely often. Fowler [1] studied the following differential equation by demonstrates both oscillatory and nonoscillatory behavior. x” + tσ |x|γ sgn x […] The post Oscillatory differential equations first appeared on John D.
