证明一个关于4维爱因斯坦orbifolds的紧性定理,它推广了Sesum的一个关于(复)2维Kahler-爱因斯坦orbifolds的收敛定理,也推广了Anderson,Bando,Kasue,Nakajima和Tian关于4维爱因斯坦流形的收敛定理.
We prove a compactness theorem for Einstein 4-orbifolds, which general- izes a theorem of Sesum on convergence of (complex) 2-dimensional Kahler-Einstein orbifolds. This also generalizes a theorem of Anderson, Bando, Kasue, Nakajima and Tian on convergence of Einstein 4-manifolds.
