摘要：

A recently proposed expansion interpolating between different actions S = S0+S1(σ) was previously defined and extensively studied with a finite ultraviolet cut-off. Here we study the renormalizability of this σ-expansion in the case of an exactly soluble theory, the Gross-Neveu model at N → ∞. We determine the necessary renormalization conditions to all orders in σ, taking into account the renormalization group equation. A crucial role is played by the asymptotic behaviour of the bare mass parameter in the massive Gross-Neveu model. © 1990.
