https://doi.org/10.1007/978-1-4939-0863-9The subject of control systems is now of increasing importance. The mathematical study of such systems is frequently of considerable complexity involving the investigation of nonlinear differential equations. However there are some systems which give rise to linear differential equations and are consequently termed linear systems.

Racial Disproportionality in PrisonThe theories of non-linear oscillations and of automatic control systems have assumed considerable importance in recent years. The mathematics is often difficult and may well involve the solution of non-linear differential equations. Few of these equations can be solved in exact terms.
