David Pollack, associate professor of mathematics, and Wai Kiu “Billy” Chan, chair and professor mathematics and computer science, recently attended a conference titled “Lattices and Applications in Number Theory” in Germany.
Pollack and Chan traveled to the Mathematisches Forschungsinstitut Oberwolfach (MFO), the first research institution established in Germany after World War II, to take part in a weeklong workshop held Jan. 17-23. Dedicated to providing an institute for international cooperative research, the MFO brings together leading experts from all over the world in order to pursue their research activities, discuss recent developments in their field, and generate new ideas. Pollack and Chan were both invited guests.
The workshop focused on the interaction of lattices with number theory, looking specifically at the application of modular forms, finite group theory, algebraic number theory, and the application of tools from linear and semi-definite optimization; applications of lattice theoretic methods to the investigation of algebraic structures; Arakelov geometry; and algebraic modular forms and Hecke operators, especially for orthogonal groups where lattice theoretic concepts play a major role.
