Restrictions on Anosov subgroups of Sp(2n,R)

Subhadip Dey, Zachary Greenberg, J. Maxwell Riestenberg

Let $n\in \mathbb{N}$ and let $\Theta \subset \{1,\dots ,n\}$ be a non-empty subset. We prove that if $\Theta$ contains an odd integer, then any $P_{\Theta }$-Anosov subgroup of ${\rm Sp}(2n,\mathbb{R}…
