Dissipative systems refer to physical systems that lose energy over time due to various internal or external factors. These systems often involve the conversion of energy from one form to another, leading to the dissipation of energy in the form of heat, sound, or other forms of energy loss. Research in dissipative systems focuses on understanding the dynamics and behavior of these systems, including how they evolve over time, the stability of their equilibrium states, and the emergence of complex behavior from simple interactions. This area of research has applications in a wide range of fields, including physics, engineering, biology, and chemistry. By studying dissipative systems, researchers can gain insight into fundamental principles of energy dissipation, nonlinear dynamics, and self-organization in complex systems.
