William Ma, professor of mathematics at Pennsylvania College of Technology, jointly authored a paper that was published recently in an international journal, Complex Analysis and Operator Theory.

The paper, titled “Two-Point Distortion for Nehari Functions,” was written with two other mathematicians, Diego Mejia, of Universidad Nacional, Colombia, and C. David Minda, of the University of Cincinnati. The work was initiated when the authors were participants in a research seminar at the Charles Phelps Taft Research Center at the University of Cincinnati.
