Defects and Permutation branes in the Liouville field theory
arXiv:0903.4422 · doi:10.1016/j.nuclphysb.2009.06.012
Abstract
The defects and permutation branes for the Liouville field theory are considered. By exploiting cluster condition, equations satisfied by permutation branes and defects reflection amplitudes are obtained. It is shown that two types of solutions exist, discrete and continuous families.
