摘要: We prove that any positive solution of the Yamabe equation on an asymptotically flat n-dimensional manifold of flatness order at least (n-2)/2 and n ≤ 24 must converge at infinity either to a fundamental solution of the Laplace operator on the Euclidean space or to a radial Fowler solution defined on the entire Euclidean space. The flatness order (n-2)/2 is the minimal flatness order required to define ADM mass in general relativity; the dimension 24 is the dividing dimension of the validity of compactness of solutions to the Yamabe problem. We also prove such alternatives for bounded solutions when n > 24. This is joint with Zheng-Chao Han and Lei Zhang.
