About Knop's action of the Weyl group on the set of the set of orbits of a spherical subgroup in the flag manifold

Nicolas Ressayre

Let $G$ be a complex connected reductive algebraic group. Let $G / B$ denote the flag variety of $G$ . Let $H$ be an algebraic subgroup of $G$ such that the set $H (G / B)$ of the…

Balanced configurations of 2n+1 plane vectors

N. Ressayre

A plane configuration {v_1,...,v_m} of vectors in {\mathbb R}^2 is said to be balanced if for any index i, the set of the det(v_i,v_j) for j\neq i is symmetric around the origin. A…

The GIT-equivalence for $G$ -line bundles

Nicolas Ressayre

Let $X$ be a projective variety with an action of a reductive group $G$ . Each ample $G$ -line bundle $L$ on $X$ defines an open subset $X^{ss} (L)$ of semi-stable points. Followi…
