发表论文

2012年毕业于美国加州大学洛杉矶分校(UCLA),主要从事几何分析、复几何与复代数几何领域的研究工作。他运用微分几何和代数几何,复分析,PDE等综合技术揭示了微分几何的中曲率和代数几何正性之 间的深刻联系,完全解决了菲尔兹奖获得者丘成桐教授在上个世纪八十年代提出的若干著名猜想。在《Invent. Math》,《Camb. J. Math.》, 《 J. Differential Geom.》,《Amer. J. Math.》,《J. Math. Pures  Appl.》,《Math. Ann.》,《J. Inst. Math. Jussieu》,《Compositio. Math.》,《J. Algebraic Geom.》,《Trans. AMS》等国际一流杂志上发表论文三十多篇。代表性论文有 (个人简历):
