Keynote Speaker:Zhou Sanming

Abstract:

Professor Zhou will talk about some recent results on the vertex-isoperimetric number of the incidence graph of unitals and the point-hyperplane incidence graph of $PG(n, q)$, where a unital is a $2$-$(n^3 + 1, n+1, 1)$ design for some integer $n \ge 2$.

Introduction to the Speaker:

Zhou Sanming, professor of the School of Mathematics and Statistics of University of Melbourne, chairman of the Australian Combinatorics Society, editor-in-chief of Australasian J. Combinatorics, and editor of J. Interconnection Networks (World Scientific) and Bulletin Malays. Math. Sci. Soc. (Springer), won the Kirkman Prize of the Institute of Combinatorics and Its Applications and the title of "Future Researcher" by the Australian Research Council. As an internationally renowned combinatorics mathematician, he mainly studied the research of algebraic graph theory and its applications, random graph process, and network optimization, and has published more than 100 academic papers.
