| Perturbative algebraic quantum field theory and the quantization of submanifold embeddings |
| Speaker: | Dr. Jochen Zahn (Univ. Vienna) |
| Abstract: | Im Rahmen des Vienna Theory Lunch Seminars.
Abstract: We review the framework of perturbative algebraic quantum field theory, which provides a mathematically rigorous formulation of perturbative quantum field theories and allows for a generalization to curved spacetimes. We present a recent application of the framework, namely the perturbative quantization of embeddings of d-dimensional submanifolds into n-dimensional Minkowski space, based on the Nambu-Goto action. The model has the status of an effective field theory. We show the absence of anomalies for any dimensions d and n, so in particular, there is no critical dimension n for the case of string theory (d=2). |

| Emergent Space and the Example of AdS_5 x S^5 |
| Speaker: | Frank Ferrari (Brussels University) |
| Abstract: | After a brief general introduction to the idea of emergent space, I will discuss a precise framework in which it is possible to build explicit models. I will then present the details in the simplest case, corresponding to the famous AdS_5XS^5 background in type IIB string theory, and also sketch some of the many possible generalizations.
