      abstract     = {The conformational and dynamical properties of isolated
                      semiflexible active polar ring polymers are investigated
                      analytically. A ring is modeled as continuous Gaussian
                      polymer exposed to tangential active forces. The analytical
                      solution of the linear non-Hermitian equation of motion in
                      terms of an eigenfunction expansion shows that ring
                      conformations are independent of activity. In contrast,
                      activity strongly affects the internal ring dynamics and
                      yields characteristic time regimes, which are absent in
                      passive rings. On intermediate time scales, flexible rings
                      show an activity-enhanced diffusive regime, while
                      semiflexible rings exhibit ballistic motion. Moreover, a
                      second active time regime emerges on longer time scales,
                      where rings display a snake-like motion, which is
                      reminiscent to a tank-treading rotational dynamics in shear
                      flow, dominated by the mode with the longest relaxation
                      time.},
