All order I.R. finite expansion for short distance behavior of massless theories perturbed by a relevant operator
R. Guida, N. Magnoli
We consider here renormalizable theories without relevant couplings and present an I.R. consistent technique to study corrections to short distance behavior (Wilson O.P.E. coeffici…

Improved Convergence Proof of the Delta Expansion and Order Dependent Mappings
Riccardo Guida, Kenichi Konishi, Hiroshi Suzuki
We improve and generalize in several accounts the recent rigorous proof of convergence of delta expansion - order dependent mappings (variational perturbation expansion) for the en…
