We study the dynamics of multidimensional contracted rotations and address a problem posed by Y. Bugeaud and J-P. Conze in Acta Arithmetica in 1999. More precisely, we show that if A is an invertible linear contraction of ℝd, then the map f: [0,1)d→ [0,1)d defined by f(x) = Ax +b (\textrmmod ℤd) is asymptotically periodic for Lebesgue almost all b∈ℝd. We also include an example of a family of multidimensional contracted rotations (d>1) not conjugate to the product of one-dimensional contracted rotations (d=1), showing that our result cannot be reduced to or derived from the one-dimensional result of Bugeaud and Conze.
