Special volume
Dedicated to Richard S. Varga on the occasion of his eightieth birthday
This special issue of the Electronic Transactions on Numerical Analysis (ETNA) is dedicated to one of its founders, Richard S. Varga, who was also an editor-in-chief for the journal for its first decade and a half: 1993-2008. Richard Varga turned 80 in October 2008, and to celebrate this milestone birthday, several dozen scientists from around the world gathered at Kent State University for a two-day symposium. This issue contains some papers presented at this meeting, and others submitted to honor Richard Varga's many contributions to mathematics for over half a century.
Richard Varga's work has had a profound influence on scientific computing. In addition, he has made many significant contributions in matrix analysis, approximation theory, and complex analysis. Richard Varga's varied research interests are reflected by the contributions in this volume. Moreover, Richard Varga has organized a large number of conferences and put Kent State University on the map in computational and applied mathematics. The Institute for Computational Mathematics in Kent, founded by Richard Varga, has hosted numerous visitors from the United States and abroad.
Congratulations, Richard!
