Effective equidistribution of unipotent orbits in homogeneous spaces of $\SL(2,\R)\ltimes(\R^2)^{k}$

Andreas StrÃ¶mbergsson, Anders SÃ¶dergren, Pankaj Vishe

Let $G=\SL(2,\R)\ltimes(\R^2)^{k}$, let $I^$ be a congruence subgroup of $\SL(2,\Z)\ltimes(\Z^2)^{k}$, and let $u_{R} = (u_{x})_{x \in R}$ be the one-parameter subgroup of $G$ given by…

A zero-one law for improvements to Dirichlet's theorem in arbitrary dimension

Andreas StrÃ¶mbergsson, Shucheng Yu

Let $I ¨ $ be a continuous decreasing function defined on all large positive real numbers. We say that a real $m \times n$ matrix $A$ is $I ¨ $ -Dirichlet if for every sufficiently large…

Extreme events and impact statistics for unipotent actions on the space of lattices

Jens Marklof, Andreas StrÃ¶mbergsson, Shucheng Yu

This paper extends a recent extreme value law for horocycle flows on the space of two-dimensional lattices, due to Kirsebom and Mallahi-Karai, to the simplest examples of rank- $k$ …
