What is non-invertible symmetry?
Non-invertible symmetry, also known as non-invertible group actions or non-invertible transformations, refers to a mathematical concept that describes symmetries in systems where the traditional notion of invertibility does not apply. In classical physics and mathematics, symmetries are typically associated with groups of transformations that can be inverted to return the system to its original state. However, in certain situations, such as quantum mechanics or topological systems, symmetries may exhibit non-invertible behavior.
History
The concept of non-invertible symmetry has its roots in the work of mathematicians and physicists studying topological phases of matter. In the 1980s, researchers discovered that certain materials exhibited unusual properties, such as quantized Hall conductivity, which defied classical understanding. These findings led to a deeper exploration of topological systems and the development of non-invertible symmetry.
