Abstract

We give an example of irrational vector θR2\pmb{\theta} \in \mathbb{R}^2 such that the set Badθ:={(η1,η2):infxNx12maxi=1,2xθiηi>0}Bad_{\pmb{\theta}} := \{(\eta_1,\eta_2): \inf_{x\in\mathbb{N}} x^{\frac{1}{2}} \max_{i=1,2} \|x \theta_i-\eta_i\|>0\} is not absolutely winning with respect to McMullen's game.
