Free circle actions on $(n - 1)$ -connected $(2 n + 1)$ -manifolds

Yi Jiang, Yang Su

In this paper, we determine those $(n - 1)$ -connected $(2 n + 1)$ -manifolds with torsion free homology that admit free circle actions up to almost diffeomorphism, provided that $n\equiv…

Topology of certain symplectic conifold transitions of $C P^{1}$ -bundles

Yi Jiang

In this paper, we prove the existence of certain symplectic conifold transitions on all $C P^{1}$ -bundles over symplectic 4--manifolds, which generalizes Smith, Thomas and Yau's exa…
