Abstract
We discuss a summability mechanism which preserves nonlinear perturbative conditions such as unitarity of the Feynman series. This condition, which relates a function f(z) and a series Σa_nz^n by the requirement ∣f(z) −Σn =^N 0a_nz^n∣ <~ Aσ^(N+1)(N+1)!|z|^(N+1) is applicable to certain divergent series.
