    • Galilean quantum gravity in 2+1 dimensions 

      Papageorgiou, Georgios (Heriot-Watt University Mathematical and Computer Science, 2010-07)
      In this thesis, we study the Galilean limit of gravity in 2+1 dimensions and give the necessary ingredients for its quantisation. We study two groups that play fundamental role in this thesis, the two-fold central extension ...
