Cell-Free MIMO integrated sensing and communication (CF-ISAC) systems can improve the capabilities of communication and sensing by utilizing distributed access points (APs). However, the imperfect channel state information (CSI) weakens the efforts of beamforming designs, resulting in performance degradation of CF-ISAC...

In this paper, we prove that the set of counterexamples to the uniform Littlewood's conjecture proposed in Bandi-Fregoli-Kleinbock, that is, the set of pairs of real numbers $(x,y)$ satisfying $$ \limsup_{Q\to +\infty}\ Q\cdot \min_{1\leq q\leq Q}\langle qx\rangle\langle qy\rangle>0, $$ is hyperplane absolute winning....
In this paper, we prove that the set of counterexamples to uniform Littlewood's conjecture proposed in \cite{BFK25}, that is, the set of real pairs $(x,y)$ satisfying $$\limsup_{Q\to+\infty}\ Q\min_{1\leq q\leq Q}\langle qx\rangle\langle qy\rangle>0$$ is hyperplane absolute winning. In particular, it has full Hausdorff...
