Abstract

Given a self-similar iterated function system Φ={ϕi(x)=ρiOix+ti}i=1m\Phi=\{ \phi_i(x)=\rho_i O_i x+t_i \}_{i=1}^m acting on Rd\mathbb{R}^d, we can generate a parameterised family of iterated function systems by replacing each tit_i with a random vector in Rd\mathbb{R}^d. In this paper we study whether a Lebesgue typical member of this family will satisfy the strong separation condition. Our main results show that if the similarity dimension of Φ\Phi is sufficiently small, then a Lebesgue typical member of this family will satisfy the strong separation condition.
