Two professors from the University of Macau\u2019s\n(UM) Department of Mathematics, namely Distinguished Professor Jin Xiaoqing and\nFull Professor Sun Haiwei, recently attended the Eighth International Congress\nof Chinese Mathematicians (ICCM 2019) held at Tsinghua University in Beijing.\nBoth professors gave a 45-minute academic report. Prof Jin was also invited to\nserve as a member of the Executive Committee of the conference.<\/p>
Initiated in\n1998 by the world-renowned mathematician Prof Shing-Tung Yau, the ICCM is a\ntriennial event that brings together Chinese and overseas mathematicians to\ndiscuss the latest developments and future directions in both pure and applied\nmathematics. It is the largest and most influential maths conference in the\nworld.<\/p>
At the conference, Prof Jin gave a\npresentation titled \u2018A Brief Survey of Matrix Manifold Computation\u2019. He discussed\nthe nonnegative inverse eigenvalue problem, and reformulated the problem as an\nunderdetermined constrained nonlinear matrix equation over several matrix\nmanifolds. He then proposed a Riemannian inexact Newton-CG method for solving\nthe nonlinear matrix equation. Under some mild assumptions, he established the\nglobal and quadratic convergence of the proposed method. Prof Sun gave a\npresentation titled \u2018Fast Algorithms for Numerical Solutions of Fractional\nPartial Differential Equations\u2019. He discretised the fractional partial differential\nequation by the implicit finite difference scheme with the shifted Grunwald\nformula. The scheme is unconditionally stable and the coefficient matrix possesses\na Toeplitz-like structure. He then explained several fast iterative methods for\nsolving the resulting systems. He also discussed how the fast Toeplitz matrix-vector\nmultiplication is utilised to lower the computational cost with only O(N log N)\ncomplexity, where N is the number of grid points.<\/p>

The research\nteam in computational mathematics, led by Prof Jin, has achieved impressive\nresults in the past decade. Team members have received two second prizes of the\nNatural Science Award from the Macao SAR government. Graduates from the\ndepartment have also won numerous awards. <\/p>
