We consider the stochastic recursion \({X_{n+1} = M_{n+1}X_{n} + Q_{n+1}, (n \in \mathbb{N})}\), where \({Q_n, X_n \in \mathbb{R}^d }\), Mn are similarities of the Euclidean space \({ \mathbb{R}^d }\) and (Qn, Mn) are i.i.d. We study asymptotic properties at infinity of the invariant measure for the Markov chain Xn under assumption \({\mathbb{E}{[\log|M|]}=0}\) i.e. in the so called critical case.
