we have been made aware of a very convincing phone scam that is focusing on our workshop participants. Participants may be contacted by phone by a firm called Business Travel Management to arrange accommodation for workshops and/or programmes. This includes a request to enter credit card information.
Please note, INI will never contact you over the phone requesting card details. We take all payments via the University of Cambridge Online store https://onlinesales.admin.cam.ac.uk/.
If you have been contacted by this company please contact us as soon as possible.
Workshop theme
During the 20th century, interactions between geometers and theoretical physicists were revolutionary in both areas, leading to such unexpected developments as mirror symmetry and the impact of topological field theory on invariants of 4-manifolds. Another momentum is now developing around new connections between number theory and physics, mainly but not exclusively through the theory of automorphic forms. We have reached a time when contacts between number theorists and physicists have the potential to generate another surge of developments.
The purpose of this interdisciplinary programme is to investigate connections between various fields of theoretical physics, in particular string theory and statistical models of crystals, and the theory of automorphic forms, mock modular forms and beyond. The non-perturbative structure of string theory has led to new uses of automorphic forms that have already appeared in number theory, as well as new exotic automorphic objects that have not yet been encountered.
This is an emergent research area with a lot of potential for cross-disciplinary collaborations with great benefit to both areas. Recent work has revealed, on the one hand, a profound significance of automorphic forms and automorphic representations for string scattering amplitudes and, on the other hand, an unexpected appearance of mock theta functions in answering key questions pertaining to quantum properties of black holes. In addition, solvable lattice models have recently appeared in connection with Eisenstein series on metaplectic groups, calling for some underlying structure that remains to be understood.
Given the current restrictions on movement, due to the ongoing pandemic, the INI intends to run this workshop virtually across 5 days. All talks and discussion sessions will be available virtually.
