Hutchinson Operator

Definition

The Hutchinson operator is a mathematical concept that generates fractals by applying a set of contraction mappings to an initial shape or point in a space. It plays a key role in the creation of iterated function systems, where each mapping reduces the size of the input and transforms it into a new output, resulting in complex structures that exhibit self-similarity and detail at every scale.
