The Open Webinar--Additive properties of sequences over semigroups and rings
主 讲 人 ：Guoqing Wang 副教授
地 点 ：钉钉群
We shall discuss some additive properties of finite sequences of elements from a commutative
semigroup or a commutative ring. The focus will be on topics in Zero-Sum Theory, a subfield of Additive
Combinatorics and Combinatorial Number Theory dealing with Ramsey-type problems with an algebraic
flavor or algebraic tools involved. During the talk, we will propose many questions and problems that
can attract the interest, we hope, of a large audience.
Guoqing Wang got his Ph.D in 2008 at Dalian University of Technology and now
works at Tianjin Polytechnic University as an associate professor of mathematics. Recently, he has been
mainly interested connections between Additive Combinatorics and semigroups & rings. He has published
more than 20 papers in J. Combin. Theory Ser. A, J. Number Theory, Semigroup Forum, Acta Arith.,
etc. His research has been supported by the National Natural Science Foundation of China (both general
program and youth program).
