Seminars

Our regular seminar takes place on Tuesdays (2 pm)  jointly with the group 'Fundamental interactions' at the Technical University of Vienna. It takes place online via BigBlueButton. If you are interested in an upcoming talk, please send an Email to olaf.krueger@univie.ac.at. I will then provide the link to the seminar. More information can be found here.

Further seminars co-organised by members of the group:

 

Upcoming Seminars:

30-11-2021: Martí Rosselló (IST Lisbon) will talk on "Rademacher expansion from symplectic symmetries of the Siegel modular form: An N=4 counting story"

Abstract: In this talk we discuss pairs of mirror dual elliptic n-folds. We show that under certain conditions mirror duality can factor into a fiber and base action, which yields mirror dual fibrations. For threefolds this allows us to study two F-theory compactifications where Higgs and tensor branches are exchanged. We give several examples and workout the exact base and fiber dictionary and further study (mirror dual) Higgs and tensor branch transitions. We then apply those those results to compute Higgs branches of 4D, N=2 rank one SCFTs.
