“…There are plenty of vector bundles with nontrivial infinitesimal deformations, but a direct sum of line bundles on the wonderful compactification has no nontrivial infinitesimal deformation (cf. Tchoudjem [31], [32], [33] and K [17]). However, there exists a line bundle with non-vanishing intermediate cohomologies in this case.…”

“…-Ce théorème généralise un des résultats de [18] et [29] qui concerne les compactifications de groupes adjoints. On retrouve aussi quelques résultats déjà connus (dans le cadre plus général des variétés sphériques) : (en effet, si µ 0 est un caractère dominant, les caractères µ tels que µ + = µ 0 sont tous dans l'orbite W * µ 0 , cf.…”
