Prof. Xi Zhang, Dean of School of Mathematics and Applied Mathematics, is visiting us with the delegation from Nanjing University of Science and Technology to discuss the articulation program with MSI. He is very kind and generous to give a research talk during his 7-hour visit to ANU. He has done a few very interesting and impressive work in geometric analysis and complex geometry, particularly for solving the Bando-Siu conjecture in Hermitian-Yang-Mills flows.
