# Dynamical Systems

**Dynamical Systems****:** ordinary differential equations, partial differential equations, delay differential equations, and differential-algebraic equations and their applications.

Dynamical systems theory is the mathematics of change. The current research of applied dynamical systems at Western includes both theoretical study and practical applications. Dynamical systems may be represented by ordinary differential equations, partial differential equations, delay differential equations, or combination of differential equations and algebraic equations. They can be discrete, continuous or impulsive systems, or combinations of these.
