UNCG Summer School in Computational Number Theory 2017

Modular Forms

summer school 2017 poster From May 22 to May 26, 2017, the University of North Carolina at Greensboro will host the UNCG Summer School in Computational Number Theory: Modular Forms.

Speakers

  • Matt Greenberg (University of Calgary)
  • Paul Gunnells (UMass Amherst)
  • Mark McConnell (Princeton University)
  • David Roe (University of Pittsburgh) /ul>

    Modular forms play an increasingly important role in number theory and arithmetic geometry. The main focus of the summer school is the study of computational aspects of modular forms and related objects. Topics may include classical modular forms and modular symbols, group cohomology and Galois representations, and lattice enumeration and isometry testing techniques to compute with spaces of modular forms for compact forms of classical groups.

    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 Science Building (campus maps and directions, Google map).
