  • 1. Mathematical system theory is a branch of mathematics that deals with modeling, analysis, and control of dynamic systems. It provides a framework for understanding the behavior of complex systems by using mathematical techniques such as differential equations, linear algebra, and probability theory. System theory is used in various fields including engineering, physics, biology, economics, and social sciences to study and design systems that exhibit dynamic behavior. By studying the interactions between the components of a system and their inputs and outputs, system theory allows us to predict and control the behavior of these systems, leading to advances in technology and scientific understanding.
