      abstract     = {We report on a micromagnetic study on domain wall (DW)
                      propagation in ferromagnetic nanotubes. It is found that DWs
                      in a tubular geometry are much more robust than ones in flat
                      strips. This is explained by topological considerations. Our
                      simulations show that the Walker breakdown of the DW can be
                      completely suppressed. Constant DW velocities above 1000 m/s
                      are achieved by small fields. A different velocity barrier
                      of the DW propagation is encountered, which significantly
                      reduces the DW mobility. This effect occurs as the DW
                      reaches the phase velocity of spin waves (SWs), thereby
                      triggering a Cherenkov-like emission of SWs. (C) 2011
