奇点解消
在代数几何学中，奇点解消问题探讨代数簇是否有非奇异的模型（即：与之双有理等价的非奇异代数簇）。在特征为零的域上，广中平祐已给出肯定答案，至于正特征的域，四维以上的情形至今（2007年）未解。

Resolution of singularities 奇点解消
In algebraic geometry, the problem of resolution of singularities asks whether every algebraic variety V has a resolution, a non-singular variety W with a proper birational map W→V. For varieties over fields of characteristic 0 this was proved in Hironaka (1964), while for varieties over fields of characteristic p it is an open problem in dimensions at least 4.
