Abstract

Let (Mj)j=1N(M_j)_{j=1}^\infty\in\mathbb{N} and (rj)j=1R+(r_j)_{j=1}^\infty\in\mathbb{R}^+ be increasing sequences satisfying some mild rate of growth conditions. We prove that there is an entire function f:CCf: \mathbb{C} \rightarrow\mathbb{C} whose behavior in the large annuli {zC:rjexp(π/Mj)zrj+1}\{ z\in\mathbb{C} : r_{j}\cdot\exp(\pi/M_{j})\leq|z|\leq r_{j+1}\} is given by a perturbed rescaling of zzMjz\mapsto z^{M_j}, such that the only singular values of ff are rescalings of ±rjMj\pm r_j^{M_j}. We describe several applications to the dynamics of entire functions.
