I'm a professor of Mathematics at the University of Georgia.
My research interests are in Capacity Theory, Arithmetic Geometry, Arithmetic Dynamics, Arithmetic aspects of Mathematical Logic, Algebraic Number Theory, Algorithms, and Computational Mathematics.
I have graduated eight doctoral students and four masters students:
· (Doctoral): Steve Donnelly, Milton Nash, Charles Pooh, Daeshik Park, Zubeyir Cinkir, Nathan Walters, John Doyle, and Kenneth Jacobs.
· (Masters): Pongsak Ajjimarangsee, Chandra French, Mee Seong Im, Renee Canfield.
Here is my current Vita.
I have written four research monographs:
· Capacity theory on algebraic curves, Lecture Notes in Mathematics 1378, Springer-Verlag, New York (1989), 437 pp.
· Existence of the sectional capacity (with C. F. Lau and R. Varley), Memoires of the American Mathematical Society, vol 145, no. 690 (2000), 130 pp.
· Potential Theory and Dynamics on the Berkovich Projective Line (with M. Baker), volume 159 in the AMS Surveys and Monographs Series (2010), 428 pp. (The file is identical to the published text; with the permission of the AMS, it is being made available online a year after its publication.)
· Capacity Theory with Local Rationality: The Strong Fekete-Szego theorem on Curves, volume 193 in the AMS Surveys and Monographs Series (2013), 437 pp. (the link is to an early draft of the book, not to the final one published)
