Abstract
We investigate the existence of minimal hypersurfaces in that are generated by the isoparametric foliation of a subsphere . By considering a generalized rotational ansatz formed by the union of homothetic copies of isoparametric leaves, we reduce the minimal surface equation to an ordinary differential equation. We prove that this construction yields a closed embedded minimal hypersurface for any choice of isoparametric hypersurface . The resulting hypersurfaces have the topological type , extending the known examples of minimal hypertori ( and ) to a broader class of topologies determined by isoparametric structures.
