- W4319989258 abstract "This article uses the iterative schemes and perturbation methods to completely solve the Han-Li conjecture, i.e. the general boundary Yamabe problem with prescribed constant scalar curvature and constant mean curvature on compact manifolds $ (M, partial M, g) $ with non-empty smooth boundary, $ dim M geqslant 3 $. It is equivalent to show the existence of a real, positive, smooth solution of $ -frac{4(n -1)}{n - 2} Delta_{g} u + R_{g} u = lambda u^{frac{n+2}{n - 2}} $ in $ M $, $ frac{partial u}{partial nu} + frac{n-2}{2} h_{g} u = frac{n-2}{2} zeta u^{frac{n}{n - 2}} $ on $ partial M $ with some constants $ lambda, zeta in mathbb{R} $. This boundary Yamabe problem is solved in cases according to the sign of the first eigenvalue $ eta_{1} $ of the conformal Laplacian with homogeneous Robin condition. The signs of scalar curvature $ R_{g} $ and mean curvature $ h_{g} $ play an important role in this existence result. In contrast to the classical method, the Weyl tensor and classification of boundary points play no role in the proof. In addition, the method is not dimensional specific. The key steps include a new version of monotone iteration scheme for nonlinear elliptic PDEs and nonlinear boundary conditions, an introduction of the perturbed conformal Laplacian, a delicate gluing skill to construct a smooth super-solution and existence of solution of local Yamabe-type equations." @default.
