On Boundary Perturbations in Liouville Theory and Brane Dynamics in Noncritical String Theories
Joerg Teschner
We study certain relevant boundary perturbations of Liouville theory and discuss implications of our results for the brane dynamics in noncritical string theories. Our results incl…
On the relation between quantum Liouville theory and the quantized Teichm"uller spaces
J. Teschner
We review both the construction of conformal blocks in quantum Liouville theory and the quantization of Teichmüller spaces as developed by Kashaev, Checkov and Fock. In both cases…
Classical and Quantum D-branes in 2D String Theory
John McGreevy, Joerg Teschner, Herman Verlinde
We investigate two classes of D-branes in 2-d string theory, corresponding to extended and localized branes, respectively. We compute the string emission during tachyon condensatio…
A lecture on the Liouville vertex operators
J. Teschner
We reconsider the construction of exponential fields in the quantized Liouville theory. It is based on a free-field construction of a continuous family or chiral vertex operators.…
