Digital Video: An Introduction to MPEG-2stion is under what conditions will there be a periodic solution? The answets for externally forced systems are quite different from those for feedback systeths that are found in Sections 3.5, 7.4, 7.5, and 8.4.

Douglas F. Aldrich,Martin SonnenscheinA mechanical or an electrical device can be constructed to a level of accuracy that is restricted by technical or economic constraints. What happens to the output if the construction is a little off specifications? Does output remain near design values? How sensitive is the design to variations in construction parameters?

Douglas F. Aldrich,Martin SonnenscheinIt is often possible to reduce stability and oscillation problems for differential equations to problems for systems of algebraic equations. These can then be studied using implicit function theorems and fixed point arguments.
