Characteristic free measure rigidity for the action of solvable groups on homogeneous spaces
Published 2 Dec 2016 in math.DS and math.GR | (1612.00537v1)
Abstract: We classify measures on a homogeneous space which are invariant under a certain solvable subgroup and ergodic under its unipotent radical. Our treatment is independent of characteristic. As a result we get the first measure classification for the action of semisimple subgroups without any characteristic restriction.
