Qiudong Wang is a Professor at the Department of Mathematics, the University of Arizona. In 1982 he received a B.S. at Nanjing University and in 1994 a Ph.D. at the University of Cincinnati.[1]
Wang is best known for his 1991 paper The global solution of the n-body problem,[2] in which he generalised Karl F. Sundman's results from 1912 to a system of more than three bodies. However, L. K. Babadzanjanz claims to have made the same generalization earlier, in 1979.[3][4]
