Introduction to Black Holes in Two Dimensions
  KTH/Nordita/SU seminar in Theoretical Physics [before December 2013]

Wednesday 14 March 2007
from 11:00 to 12:00
at FB41
Speaker : Daniel Grumiller (MIT)
Abstract : I review how two dimensional dilaton gravities arise in various contexts, e.g. from dimensional reduction in general relativity and as low energy effective action in type 0A string theory. All these models are classically integrable. Semi-classically the Hawking effect arises from the conformal anomaly. Non-perturbative path integration over geometry and dilaton is possible and leads to non-local, non-polynomial effective matter actions. Results for the lowest order S-matrix for s-wave gravitational scattering are presented.
