Topological dynamics

Definition

Topological dynamics is a branch of mathematics that studies the behavior of dynamical systems under continuous transformations, focusing on the topological properties and structures of these systems. This field investigates how the system evolves over time while considering concepts such as continuity, compactness, and convergence. It plays a crucial role in understanding complex systems, particularly in the context of iterative processes and fractal patterns.
