UNCG Summer School in Computational Number Theory 2015

Zeta Functions -- New Theory and Computations

summer school 2015 poster From May 18 to May 22, 2015, the University of North Carolina at Greensboro is hosting a summer school entitled Zeta Functions -- New Theory and Computations.

The speakers will be

The summer school in computational number theory fills a gap in the education of many graduate students. Most graduate courses in number theory take a mainly theoretic approach with very little emphasis on the computational aspects of the subject. The goal of the UNCG Summer School in Computational Number Theory is to complement this with a constructive-algorithmic approach. Many of the algorithms used for number theoretic computations are non-trivial, which makes it difficult to cover them in a standard course.

The subjects we plan to cover this year include: A historic approach to the Riemann Zeta function; the distribution of the zeros of zeta functions and their and their derivatives; horizontal cuts of the critical strip; efficient evaluation of zeta functions and their derivatives; related functions; gaps between primes; and twin primes.

On a typical day, external and local experts give talks in the morning, and in the afternoon students solve problems related to this material. The talks early in the week introduce the students to the subject. Talks later in the week 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 are aimed at increasing the students’ understanding of the material by working with it.

Schedule

All talks will take place in Room 213 in the Petty Building (campus maps and directions).

Some Resources

Some Sage can help with experimenting with zeta functions. The LMFDB contains a database of L-functions. We also have an example Arb program.
