Some differences between difference equations and differential equations. (English) Zbl 0856.34036

This is an expository paper. The author discusses some instances in which analogues fail to hold which might be expected between the behavior of solutions of differential equations and difference equations, focusing particularly on questions related to boundedness and oscillation. The author gives three examples to explain this different behaviour.
