We show that for any $\epsilon< 1$ and any $\mathcal {T} $drifting away from walls', Dirichlet's Theorem cannot be $\epsilon $-improved along $\mathcal {T} $ for Lebesgue …
The modern study of dynamical systems on homogeneous spaces has roots in classical dynamics and classical number theory. For example, the geodesic flow on a surface of …
Abstract Consider G= SL _ d (R) G= SL d (R) and Γ= SL _ d (Z) Γ= SL d (Z). It was recently shown by the second-named author (Shi, Pointwise equidistribution for one parameter …

Recently Mohammadi and Salehi-Golsefidy gave necessary and sufficient conditions under which certain translates of homogeneous measures converge, and they determined the …
We prove an avoidance principle for expanding translates of unipotent orbits for some semisimple homogeneous spaces. In addition, we prove a quantitative isolation result of …

Let G be a real Lie group, a lattice and a connected semisimple subgroup without compact factors and with finite center. We define the notion of H-expanding measures on H and …
We study distribution of orbits of a lattice Γ⊆\SL(n,R) in the the space V_n,l of l-frames in R^n (1≤l≤n-1). Examples of dense Γ-orbits are known from the work of Dani, Raghavan …
