Bifurcation is a concept in mathematics and physics that describes a qualitative change in the behavior of a system when a parameter is varied. In dynamical systems, it marks the point where a stable state can split into two or more states, or where stability is lost and new patterns of motion appear. Bifurcations can lead to phenomena such as sudden transitions, oscillations, or chaotic behavior. The term is also used more generally for any situation where a single path, structure, or solution divides into two branches. Studying bifurcations helps in understanding complex systems in fields like mechanics, biology, and economics.
