A Herman ring is a concept in the field of dynamical systems, specifically in complex dynamics. It refers to a type of invariant set that arises in the study of maps, particularly those that are holomorphic or involve complex functions. A Herman ring is associated with a certain type of periodic point and is characterized by the presence of annular regions where the dynamics exhibit quasiconformal or non-unique properties.
