Exact S-matrix for two-dimensional string theory

摘要: Abstract We formulate simple graphical rules which allow explicit calculation of nonperturbative c = 1 S -matrices. This allows us to investigate the constraint unitarity, indeed out some theories. Nevertheless, we show that there is an infinite parameter family nonperturbatively unitary dependence -matrix on one these parameters. In particular, study analytic structure, background and high-energy behavior The scattering amplitudes display interesting resonant both at high energies in complex energy plane.
