报告摘要: The family of spaces F(p,q,s) was introduced by the speaker in 1996. Since then there has been a great development on the theory of F(p,q,s) spaces, due to the fact that these spaces include many classical function spaces as special cases, such as Bloch type spaces, Qp spaces, BMOA, weighted Bergman spaces, weighted Dirichlet spaces and analytic Besov spaces, and have natural connections with many other areas of mathematics. We present basic properties and some recent results on the theory of F(p,q,s) spaces.

报告人简介：Ruhan Zhao is a SUNY Distinguished Professor in mathematics at the State University of New York Brockport. He obtained PhD in mathematics at University of Joensuu (now University of Eastern Finland) in 1996. In 1998-99, he held a post-doctoral fellowship at Kyoto University, sponsored by the Japanese Society of Promotion of Science (JSPS). He has published over 70 research papers on spaces of analytic functions and operator theory in journals such as Math. Ann., Trans. Amer. Math. Soc., Proc. Amer. Math. Soc., Indiana Univ. Math. J., Michigan Math. J., Pacific J. Math., J. London Math. Soc., etc. In 1995 he introduced the Qp spaces with his coauthors, Rauno Aulaskari and Jie Xiao. In 1996 he introduced F(p,q,s) spaces. The Qp spaces and the F(p,q,s) spaces have been extensively studied by mathematicians all over the world since they were introduced. In 2010 Mathematics Subject Classification (MSC) it assigned Qp spaces a classification number, 30H25. In 2014 Dr. Zhao received the SUNY Chancellor’s Award for Excellence in Scholarship and Creative Activities. Dr. Zhao is also a science fiction writer who published dozens of science fiction stories in China.
