Research Interest
Number Theory, Combinatory Theory, Graphs Theory

Research in Progress
1. In 1935, Erdos obtained the upper bounds for Ramsey numbers
2. In 1968, Walker proved
3. In 1998, I and Zhang Kemin proved

l From 2001, I generalized van der Waerden numbers to and the generalized van der Waerden numbers on circles, and convert the solution of van der Waerden numbers to the solution of the systems of linear inequality equations. This work has been done.
