| Generic spacelike singularities: The BKL conjecture |
| Speaker: | Paul Klinger (Univ. Wien) |
| Abstract: | im Rahmen des GAP-Seminars: While the singularities theorems of Penrose and Hawking show the existence of singularities under
quite general assumptions they do not give any information about their structure. The BKL conjecture is an att -
empt to give a detailed description of generic spacelike singularities. It is unproven but supported by numerical
evidence and simplified models. I will describe the Hamiltonian Billiards formulation of the conjecture and give
some heuristic arguments in it its favor. Finally, I will present a rigorous result in the simplified "non-chaotic"
case. |

| Time: | 11:00 |
| Duration: | 60 min |
| Location: | Arbeitsgruppe Gravitation, Währinger Strasse 17, Seminarraum A, 2. Stock, 1090 Wien |
| Contact: | M. Bauer (Fak. Math, U.V.), V. Branding (Fak. Math, T.U.), D. Fajman (Fak. Phys, U.V.), J. Joudioux (Fak. Phys, U.V.) |
| Speaker: | Cheng Peng (ETH Zurich) |
| Abstract: | This talk contains two parts. Firstly I will discuss some recent developments of higher spin theories in the context of AdS_3/CFT_2 correspondence, with special emphasis on the relation to String theory. The second part of the talk will be devoted to the Schroedinger type of solutions of the Vasiliev higher spin theory in D>3 dimensions.
