Form-factors in the $SU(2)$-invariant Thirring model

Explicit formulae are obtained for the matrix coefficients of currents and the stress-energy tensor in the $SU(2)$-invariant Thirring model the operators defined by these formulae are shown to commute with each other on space-like intervals,. The singularities of the currents1s commutators at the origin are determined. Bubl. – 12.
