Algebras with operator and Campbell-Hausdorff formula

Abstract

We introduce some new classes of algebras and establish within these algebras Campbell-Hausdorff-like formulae. We describe the application of these constructions to the problem of the connectivity of the Feynman graphs corresponding to Green functions in quantum fields theory.
