Uniformization theorems: Between Yamabe and Paneitz

Cheikh Birahim Ndiaye, Yannick Sire and Liming Sun

Vol. 314 (2021), No. 1, 115–159

This paper is devoted to several existence results for a generalized version of the Yamabe problem. First, we prove the remaining global cases for the range of powers γ (0,1) for the generalized Yamabe problem introduced by Gonzalez and Qing. Second, building on a new approach by Case and Chang for this problem, we prove that this Yamabe problem is solvable in the Poincaré-Einstein case for γ (1,min{2, n 2 }) provided the associated fractional GJMS operator satisfies the strong maximum principle.
