Abstract
For α,β,δ∈[0,1],α+β=1 we consider sets BAD∗(α,β;δ)={ξ=(ξ1,ξ2)∈[0,1]2:,p∈Ninfmax{(plog(p+1))α∣∣pξ1∣∣,(plog(p+1))β∣∣pξ2∣∣}≥δ}. We prove that for different (α1,β1),(α2,β2),α1+β1=α2+β2=1 and δ small enough BAD∗(α1,β1;δ)⋂BAD∗(α2,β2;δ)=∅. Our result is based on A. Khintchine's construction and an original method due to Y. Peres and W. Schlag.
