Boundary value problem for black rings
Yoshiyuki Morisawa, Shinya Tomizawa, and Yukinori Yasui

We study the boundary value problem for asymptotically flat stationary black ring solutions to the five-dimensional vacuum Einstein equations. Assuming the existence of two additional commuting axial Killing vector fields and the horizon topology of $\rm \rm S^1\times \rm S^2$, we show that the only asymptotically flat black ring solution with a regular horizon is the Pomeransky-Sen'kov black ring solution.
