UPB Math Professer Presents Paper

Dr. Yong-Zhuo Chen, University of Pittsburgh at Bradford professor of mathematics presented a paper at the American Mathematical Society’s Eastern Sectional meeting at the New Jersey Institute of Technology in Newark, N.J.

Chen’s paper, “Some Contractive Type Mappings and Their Application to Difference Equations,” used a new method to solve a type of difference equation. Difference equations are used to model phenomena in biology, ecology, physiology, physics, engineering and economics.

The paper has also been accepted for publication in the Journal of Difference Equations and Applications.

Chen was born in China. He obtained his Master of Science degree in mathematics from Shanghai Normal University and taught there as an instructor for a couple of years.

He came to the United States at the end of 1983 to attend the University of Pittsburgh, where he received his doctorate in mathematics in 1988.

Chen’s doctoral work was in the field of harmonic analysis and he, together with his advisor, initiated the study of several new classes of Hardy spaces, which have been developed considerably by other mathematicians since then.

After working as a visiting assistant professor at Bowling Green State University for one year, he began his career at Pitt-Bradford in 1989.

Since coming to Pitt-Bradford, his research interest has shifted to the field of nonlinear operators. He has published more than 30 refereed papers, which include several co-authored articles with students, in college-level mathematics journals.

He is also chairman of the division of physical and computational sciences. He lives in Bradford.
