A cyclic complex is a specific type of chain complex that arises in the study of cyclic cohomology, where the structure is defined by a cyclic action on the complex. This means that it includes an additional symmetry involving rotation, making it useful for analyzing algebraic structures with cyclic properties, such as in noncommutative geometry.
