[hep-th] seminar

[Branislav Cvetkovic]

Postovane kolege,
u petak 20. jula  u 11 h na Institutu za fiziku, u sali 10,
Blagoje Oblak sa Unverziteta u Briselu ce odrzati seminar pod naslovom 
"Symmetries of 3d asymptotically flat space-times". Apstrakt
vam prosledjujem  u prilogu.

                              Pozdrav Branislav

Apstrakt:

I will review basic results on asymptotic symmetries of 
three-dimensional asymptotically flat space-times. Beginning with 
asymptotic Killing vectors, I will continue with the definition of the 
BMS3 group and the bms3 algebra. After that, I shall discuss the most 
general central extension of bms3 and I will show that surface charges 
of asymptotically flat space-times satisfy a special case of this 
centrally extended algebra.
Finally, I will say a few words on highest-weight representations of 
bms3.
