Gaoyong Zhang is an American mathematician. He is professor at the Courant Institute of Mathematical Sciences at New York University in New York City. His main research interests are convex geometry and its connections with analysis and information theory.

Biography

Gaoyong Zhang graduated from Temple University in Philadelphia with a PhD in 1995. His advisor was Eric Grinberg. ^[1] Before he became a professor at the Courant Institute at NYU, he was a member of the Institute of Advanced Study. ^[2]

Zhang became an Inaugural Fellow of the American Mathematical Society ^[3] in 2012. He is a member of the editorial board at Advanced Nonlinear Studies (De Gruyter) ^[4] and at the Proceedings of the American Mathematical Society. ^[5]

Work

Gaoyong Zhang is known for his inverse of the Petty projection inequality, ^[6] one of the few inequalities in convex geometry where simplices were proved to be extremals. He obtained a positive solution for the Busemann–Petty problem in ${\displaystyle R^{4}}$. ^[7] He is known for his contributions (in collaboration with Erwin Lutwak and Deane Yang) to the L_p Brunn Minkowski Theory and, in particular, his solution to the logarithmic Minkowski problem. ^[8]
