"Boundary CFTs and their central charges"
by Vladimir Procházka (Uppsala University)
Friday, November 30th, 2018 from 14:00 (Europe/Budapest)
at KFKI campus ( Bldg.3. Conference Room )
Abstract:
I will introduce basic some basic properties of boundary CFTs focusing on
the 3-dimensional case with planar boundary. The emphasis will be given on
the definition of energy-momentum tensor, its correlators and the associated
anomalies. I will then move on to discuss the momentum space representation
of these correlators and use it to determine the boundary Ricci scalar
anomaly and its physical interpretation. In the remainder of the talk I will
describe how to apply these methods using the method of images to compute
the anomaly in explicit examples.
