Abstract: A pair $(A,\textbf{b})$ of a real $m\times n$ matrix $A$ and $\textbf{b}\in \mathbb{R}^{m}$ is said to be infinitely badly approximable if $$ \begin{align*} & \liminf_{\textbf{q}\in\mathbb{Z}^{n}, \|\textbf{q}\|\to\infty} \|\textbf{q}\|^{\frac{n}{m}}\|A\textbf{q}-\textbf{b}\|_{\mathbb{Z}} =\infty, \end{align*} $$where $\|\cdot \|_{\mathbb{Z}}$ denotes the distance… read more here.
