Let A be a commutative C U -algebra with identity and open unit ball B. We study holomorphic functions F: B Βͺ B that are idempotent under composition and establish necessary and sufficient conditions for a set R : B to be the image Ε½ of B under such an idempotent function. In other words, R is a hol
