UNCG Summer School in Computational Number Theory 2013

Computational Algebraic Number Theory

summer school 2013 poster

From May 20 to May 24, 2013, the University of North Carolina at Greensboro is hosting a summer school entitled Computational Algebraic Number Theory. This summer school will cover fundamental algorithms for number fields. It will complement what students learn in a standard course on algebraic number theory. The methods presented, such as methods for arithmetic, integral basis, unit groups, class group, and Galois group computations, are essential for further computations in number theory and algebraic geometry.

On a typical day, external and local experts will give talks in the morning, and in the afternoon students will solve problems related to this material. The talks early in the week will introduce the students to the subject. Talks later in the week will cover related areas of current research and unsolved problems. The problems given to the students might be of a theoretical nature but could also involve programming problems and computer experiments. All problems will be aimed at increasing the students’ understanding of the material by working with it.


All talks will take place in Room 213 in the Petty Building (29 on the campus map). See directions for additional maps and directions.
