Isoparametric foliation and a problem of Besse on generalizations of Einstein condition
Zizhou Tang, Wenjiao Yan
The focal sets of isoparametric hypersurfaces in spheres with g = 4 are all Willmore submanifolds, being minimal but mostly non-Einstein ([TY1], [QTY]). Inspired by A.Gray's view,…

Isoparametric functions on exotic spheres
Chao Qian, Zizhou Tang
This paper extends widely the work in \cite{GT13}. Existence and non-existence results of isoparametric functions on exotic spheres and Eells-Kuiper projective planes are establish…

-invariant and a problem of Bérard-Bergery on the existence of closed geodesics
Zizhou Tang, Weiping Zhang
We use the -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 Bérar…
