Announcements

We would like to announce the Lecture Series on "Modular Forms in String Compactifications" by Thorsten Schimannek (Wien). It will be held as a Zoom meeting.

Topics will include:
- Basics of modular forms, Jacobi forms and string compactifications
- Symmetries of string theories on tori
- Modularity from Calabi-Yau compactifications
- Jacobi forms and swampland conjectures

For more information and the registration form please visit the event webpage.

Claude Duhr (CERN) will give a Lecture Series on "New Approaches to Feynman Integrals" on March 15 - 19, 2021, as a Zoom meeting. .

Abstract: Feynman integrals are the backbone of all higher-order calculations in perturbative quantum field theory. They are not only of formal interest, but they are also key to performing precise calculations for experiments. In these lecture we review some recent developments in the understanding of the mathematics underlying Feynman integrals. We focus in particular on tools inspired from modern number theory and the theory of motivic periods, which have been instrumental in some of the most advanced computations for experiments in collider physics.

• Richard Dawid (Stockholm University)
• The Current Status of Non-Empirical Confirmation
• Zoom meeting

Abstract: Non-empirical and meta-empirical confirmation were initially proposed as concepts for understanding the degree of trust many theoretical physicists have developed in empirically unconfirmed theories such as string theory. In recent years, the analysis has broadened. The basic arguments of meta-empirical theory assessment are now taken to play an implicit but central background role in all confirmation, be it empirical or non-empirical. To the extent confirmation is about generating trust in a scientific theory, meta-empirical theory assessment must be involved. This perspective contributes to a clearer understanding of the continuities between empirical and non-empirical confirmation. It also allows for a more nuanced appraisal of research contexts where both forms of confirmation happen side by side. In the talk, I will present the rationale behind the described view and illustrate it with examples from high energy physics and cosmology.

Two preliminary lectures to the postponed Bethe Forum "Modular Flavor Symmetries" will take place as a Zoom meeting on May 3 - 4, 2021. The speakers are Gui-Jun Ding (Hefei, CUST) and Saúl Ramos-Sánchez (Mexico).
