Is Li Zenghu good at math?

Li Zenghu is good at mathematics. Li Zenghu has been engaged in mathematics education for decades and has rich educational experience. He knows how to start and learn mathematics, and his teaching is lively and interesting, which makes people understand clearly. According to relevant public information, Li Zenghu, male, was born in Hejian County, Hebei Province in June 1962 165438, Ph.D., chairman of China Probability and Statistics Society, professor and doctoral supervisor of School of Mathematical Sciences of Beijing Normal University. Engaged in research, research fields include measure-valued Markov processes, branched Markov processes, stochastic differential equations, stochastic environmental models, stochastic financial models, etc. The purpose of this study is to understand the natural phenomena described by these models theoretically. In the study of branching process with immigrants, the concept and method of "oblique convolution semigroup" are put forward, which is considered by international colleagues to "play a key role" in this study and develop "a set of theories".
