      Harvey, John; Searle, Catherine (Deutsche Mathematiker Vereinigung, 2021-10-01)
      We classify positively curved Alexandrov spaces of dimension 4 with an isometric circle action up to equivariant homeomorphism, subject to a certain additional condition on the infinitesimal geometry near fixed points which ...
