Abstract

We give a prescription for the one-loop renormalisation of the imaginary parts of vertex functions in gø4, which are generated when gR < 0 is non-perturbative in ɛ. This fixed point determines the imaginary parts of the critical exponents which are generated when ɛ < 0, and allows us to determine the high-order behaviour of the perturbation series in E for these exponents. The generalisation of these ideas to the O(n) symmetric g(ø2)2 model is also given.
