Ramírez's problems and fibers on well approximable set of systems of affine forms
Bing Li, Bo Wang
We show that badly approximable matrices are exactly those that, for any inhomogeneous parameter, can not be inhomogeneous approximated at every monotone divergent rate, which gene…

Metric results for the eventually always hitting points and level sets in subshift with specification
Bo Wang, Bing Li
We study the set of eventually always hitting points for symbolic dynamics with specification. The measure and Hausdorff dimension of such sets are obtained. Moreover, we establish…
