ABOUT THE LECTURE

Polynomial interpolation is a basic method to approximate smooth functions and serves as a basis of spectral collocation methods. In particular, this procedure is known as spectral interpolation when the interpolation nodes are the zeros and extrema of orthogonal polynomials. In this talk, I will review some results on computational and theoretical aspects of spectral interpolation, including barycentric formula and some interesting properties of orthogonal polynomials.

ABOUT WANG HAIYONG

In School of Mathematics and Statistics of Central South University, he got Bachelor of Science degree in July 2005, and studied for master’s and doctor’s degree of computing mathematics respectively in Sept. 9 and Sept. 2007. During March 2011 to Dec. 2012, he served as a post doctor at the Department of Computing Mathematics in Catholic University of Leuven, in Belgium. Then he has worked as a associate professor in Huazhong University of Science and Technology since 2013. He mainly worked on researches of some areas, including numerical methods of highly oscillatory problems, numerical integrals, spectral method, barycentric interpolation. Taking charge of one project of both Natural Science Foundation of China and Youth Fund, he has published about a dozen of academic papers on international authoritive computing mathematics journals, some discoveries of which were included in the book of Approximation Theory and Approximation Practice, written by Trefethen, fellow of Royal Society.
