Uniqueness of warped product Einstein metrics and applications
Chenxu He, Peter Petersen, William Wylie
We prove that complete warped product Einstein metrics with isometric bases, simply connected space form fibers, and the same Ricci curvature and dimension are isometric. In the co…

Warped product rigidity
Chenxu He, Peter Petersen, William Wylie
In this paper we study the space of solutions to an overdetermined linear system involving the Hessian of functions. We show that if the solution space has dimension greater than o…
