Katrina Barron: What modular invariance properties should we expect from a Conformal Field Theory?

mardi 14 oct. 2025, 10:30 → 11:30 Europe/Paris

The geometry of propagating strings in Conformal Field Theory, naturally gives rise to certain modular invariance properties for trace-like functions defined on the vertex operators of propagating fields. We will discuss some of the well-known and lesser-known settings for these modular invariance properties...
