distribution of dense lattice orbits on homogeneous spaces
abstract:
let $h < g$ both be noncompact connected semisimple real algebraic groups and $\gamma < g$ be a lattice. in the work of gorodnik--weiss, they showed that the distribution of dense $\gamma$-orbit on homogeneous space $g/h$ is asymptotically the same as $g$-orbit on $g/h$. one key ingredient in their proof is shah's theorem derived from the famous ratner's theorem. in this talk, we report an effective version of this result in the case $(g, h, \gamma) = (\mathrm{sl}_3(\mathbb{r}), \mathrm{so}(2, 1), \mathrm{sl}_3(\mathbb{z}))$. the proof uses recent progress by lindenstrauss--mohammadi--
