Entropy Bounds for Self-shrinkers with Symmetries

Abstract: In this work we derive explicit entropy bounds for two classes of closed self-shrinkers: the class of embedded closed self-shrinkers recently constructed in arXiv:2207.04851 using isoparametric foliations of spheres, and the class of compact non-spherical immersed rotationally symmetric self-shrinkers. These bounds generalize the entropy bounds found in arXiv:2202.08641 on the space of complete embedded rotationally symmetric self-shrinkers.
