Abstract

Light Cone Quantization Unitarization Factor Bulk Theory Topological Charge Trigonometric Solution
We construct integrals of motion (IM) for the sine-Gordon model with boundary at the free Fermion point (β2 = 4π) which have a simple form. These IM determine the boundary S matrix. We also provide an Ansatz for the fractional-spin IM away from the free Fermion point (β2 ≠ 4π).
