Abstract
Let Γ = Z A + Z n ⊂ R n be a dense subgroup of rank n + 1 and let \( \hat{w} \)(A) denote the exponent of uniform simultaneous rational approximation to the generating point A. For any real number v ≥ \( \hat{w} \)(A), the Hausdorff dimension of the set B v of points in R n that are v-approximable with respect to Γ is shown to be equal to 1/v.
