The Feynman transform

Overview

The Feynman transform is an operation on the category of twisted modular operads. It gives a way to parametrize various versions of the Kontsevich’s graph complex, by various modular operads. Every modular operad is in particular cyclic (some say “symplectic”). The Feynman transform, up to a shift, reduces to the cobar operad? of the underlying cyclic operad.

The name “Feynman transform” is due to Getzler and Kapranov.
