摘要:
We use the eta-invariant of Atiyah Patodi Singer to compute the Eells Kuiper invariant for the Eells Kuiper quaternionic projective plane. By combining with a known result of Berard-Bergery, it shows that every Eells Kuiper quaternionic projective plane carries a Riemannian metric such that all geodesics passing through a certain point are simply closed and of the same length.
