Some automorphism groups are linear algebraic
Michel Brion
Consider a normal projective variety , a linear algebraic subgroup of Aut(), and the field of -invariant rational functions on . We show that the subgroup of Au…

Some combinatorial aspects of generalised Bott-Samelson varieties
Michel Brion, S. Senthamarai Kannan
We obtain two combinatorial results: an equality of Weyl groups and an inequality of roots, in the setting of generalised Bott-Samelson resolutions of minuscule Schubert varieties.…

Minimal rational curves on generalized Bott-Samelson varieties
Michel Brion, S. Senthamarai Kannan
We investigate families of minimal rational curves on Schubert varieties, their Bott-Samelson desingularizations, and their generalizations constructed by Nicolas Perrin in the min…
