We construct a conformal product structure on using the Reeb foliation. This is the first example of a conformal product structure on a compact simply connected manifold whic…

Conformal product structures on compact manifolds with constant sectional curvature
Xianfeng Jiang
We prove that compact non-flat manifolds of constant sectional curvature admit no conformal product structure. In the flat case, we show that in dimensions at least three every con…
