Diophantine approximation on subspaces of and dynamics on homogeneous spaces
arXiv:1606.02399
Abstract
In recent years, the ergodic theory of group actions on homogeneous spaces has played a significant role in the metric theory of Diophantine approximation. We survey some recent developments with special emphasis on Diophantine properties of affine subspaces and their submanifolds.
