On the $\alpha$-representation of Feynman integrals

B. M. Stepanov


Abstract: Graph theory is used to prove a formula for the integral over the internal momenta in the $\alpha$-representation of a Feynman integral. The distinctive feature of this formula is its explicit symmetry with respect to the choice of a tree in the graph.
