The Version of Record is available online at: https://doi.org/10.1007/s00209-025-03861-0We conclude the classification of isoparametric (or equivalently, polar) foliations of complex and quaternionic projective spaces. This is done by investigating the projections of certain inhomogeneous isoparametric foliations of the 31-sphere under the respective Hopf fibrations, thereby solving the last remaining open cases.engPolar foliationIsoparametric foliationFKM foliationSingular Riemannian foliationHomogeneous foliationComplex projective spaceQuaternionic projective spacejournal article10.1007/s00209-025-03861-01432-1823open access
