On geometry of symplectic involutions

Mark Pankov

Let $V$ be a $2 n$ -dimensional vector space over a field $F$ and $Ω$ be a non-degenerate symplectic form on $V$ . Denote by $H_{k} (Ω)$ the set of all $2 k$ -dimensional sub…

On geometry of linear involutions

Mark Pankov

Let $V$ be an $n$ -dimensional left vector space over a division ring $R$ and $n \geq 3$ . Denote by $G_{k}$ the Grassmann space of $k$ -dimensional subspaces of $V$ and put…
