## 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.

## Courses

I am on sabbatical leave in Spring 2020 and Fall 2020.

## Book

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.

## 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.
