Query: Form factors of SU(N) invariant Thirring model   We obtain a new integral formula for solutions of the rational quantum
Knizhnik-Zamolodchikov equation associated with Lie algebra sl_{N} at level
zero. Our formula contains the integral representation of form factors of SU(N)
invariant Thirring model constructed by F. Smirnov. We write down recurrence
relations arising from the construction of the form factors. We check that the
recurrence relations hold for the form factors of the energy momentum tensor.
