Geometry of configuration spaces of tensegrities

Franck Doray, Oleg Karpenkov, Jan Schepers

Consider a graph G with n vertices. In this paper we study geometric conditions for an n-tuple of points in R^d to admit a tensegrity with underlying graph G. We introduce and inve…

Variétés homogènes sous $\PGL_n$

Franck Doray

Let $A$ be an Azumaya algebra over a field. If $G$ is the group of automorphisms of $A$ and $X$ denotes a projective homogeneous variety under $G$ , we construct in a very explicit…
