[hep-th] seminar

[Branislav Cvetkovic]

Postovane kolege,
u petak 18. septembra u 11 h na Institutu za fiziku u sali 300 odrzacu 
seminar pod naslovom Asimptotska struktura topoloski masivne gravitacije 
u "spacelike stretched" AdS sektoru. Apstrakt vam prosledjujem u prilogu.
                                              Pozdrav Branislav
                                
Abstract
We introduce a natural set of asymptotic conditions in the spacelike 
stretched AdS sector of topologically massive gravity. The Poisson bracket 
algebra of the canonical generators is shown to have the form of the semi-
direct sum of a u(1) Kac-Moody and a Virasoro algebra, with central charges. 
Using the Sugawara construction, we prove that the asymptotic symmetry 
coincides with the conformal symmetry, described by two
independent Virasoro algebras with central charges. The result is in 
complete agreement with the hypothesis formulated by D. Anninos et al.
