Immediate renormalization of complex polynomials

Abstract

A cubic polynomial PP with a non-repelling fixed point bb is said to be \emph{immediately renormalizable} if there exists a (connected) quadratic-like invariant filled Julia set KK^* such that bKb\in K^*. In that case exactly one critical point of PP does not belong to KK^*. We show that if, in addition, the Julia set of PP has no (pre)periodic cutpoints then this critical point is recurrent.
