Contribution to the proceedings of Schladming 1995. A review of the form factor approach and its utilisation to determine the space of local operators of integrable massive quantum theories is given. A few applications are discussed.
A method to determine the full structure of the space of local operators of massive integrable field theories, based on the form factor bootstrap approach is presented. This method is applied to the integrable perturbations of the Ising conformal point. It is found that the content of local operators can be expressed in terms of fermionic sum representations of the characters $\c(q)$ of the Virasoro irreducible representations of the minimal model $\M_{3,4}$. The space of operators factorises into chiral components as $Z=\sum \c(q) \c(\q)$, but with the relation $\q=q^{-1}$.
