Four relations on the set of point-hyperplane anti-flags

Mark Pankov, Antonio Pasini

There are precisely four arrangements of two point-hyperplane anti-flags. We consider the corresponding relations on the set of such anti-flags and show that each of them can be re…

On the $1$ -cohomology of $SL (n, K)$ on the dual of its adjoint module

Ilaria Cardinali, Luca Giuzzi, Antonio Pasini

Given a field $K$ , for any $n \geq 3$ the first cohomology group $H^{1} (G_{n}, A_{n}^{*})$ of the special linear group $G_{n} = SL (n, K)$ over the dual $A_{n}^{*}$ of its…

The relatively universal cover of the natural embedding of the long root geometry for the group $SL (n + 1, K)$

I. Cardinali, L. Giuzzi, A. Pasini

The long root geometry $A_{n, {1, n}} (K)$ for the special linear group $SL (n + 1, K)$ admits an embedding in the (projective space of) the vector space of t…
