　　摘要: The weak cosmic censorship conjecture, which states that for generic asymptotically flat initial data, the future null infinity is always complete, is one of the most important questions in General Relativiy. We consider two intersected null cones, the outgoing one of which intersects with future null infinity. The data on the outgoing null cone decay suitably. We show that the solution of Einstein equations always exists in a uniform neighbourhood of the outgoing null cone. In particular, the future null infinity can always extend in the retarded time locally, which should be considered as the first step towards the weak cosmic censorship. This is a joint work with Junbin Li.
