Rob Benedetto's Homepage

I'm a Professor of Mathematics in the Department of Mathematics and Statistics here at Amherst College.

Previously, I was: a graduate student in the Math Department at Brown University, graduating in 1998;
then a Visiting Assistant Professor in the Math Department at the University of Rochester, from 1998 to 2000, and
then an NSF-sponsored Research Postdoc in the Math Department at Boston University, from 2000 to 2002.

The main focus of my research is arithmetic dynamics, which is the study of discrete dynamical systems in a number-theoretic context.
My particular interests include non-archimedean dynamics, arboreal Galois representations, and preperiodic points, preperiodic subvarieties, and points of small canonical height over global fields.

Math 350, Section 02 (Groups, Rings and Fields), Fall 2022


My book Dynamics in One Non-Archimedean Variable has appeared.

It is a graduate-level textbook on the dynamics of rational functions defined over p-adic and other non-archimedean fields, published by the American Mathematical Society.

Five College Number Theory Seminar

Conference for David Cox

My colleague David Cox retired in Summer 2019. Amherst College hosted a conference in his honor:

Ideals, Varieties, and Applications, a mathematics research conference honoring David and celebrating his influence in several areas of algebraic geometry and commutative algebra. It took place at the Amherst College Science Center, from Monday, June 10 through Friday, June 14, 2019.
