Dr. Daniel Biles, associate professor in the Math & Computer Science Department, recently had two papers accepted for publication. “Nystrom methods and singular second-order differential equations,” which was co-authored with David Benko, Mark P. Robinson and John S. Spraker, was recently published in Computers and Mathematics with Applications. The same group also was recently published in Mathematical and Computer Modelling for the article titled “Numerical approximation for singular second-order differential equations.”
