Abstract
The interplay between topology and dynamics is discussed by introducing the notion of topological degeneracy according to which two topological droplet textures (hedgehog-like and vortex-like, respectively) having different ground-state energies are characterized by the same topological charge. This work was partially supported by MIUR-PRIN 2010-11 Project2010ECA8P3 "DyNanoMag". [1] T. Moriya, Phys. Rev. Lett. 4, 228 (1960). [2] R.
