Title: The Ricci flow on solvmanifolds of real type,
Abstract: We show that for any solvable Lie group of real type, any homogeneous Ricci
flow solution converges in Cheeger-Gromov topology to a unique non-flat
solvsoliton, which is independent of the initial left-invariant metric. As an
application, we obtain results on the isometry groups of non-flat solvsoliton
metrics and Einstein solvmanifolds.
