Mathematical renormalization in quantum electrodynamics via noncommutative generating series

Abstract

In this work, we focus on on the approach by noncommutative formal power series to study the combinatorial aspects of the renormalization at the singularities in $\{0,1,+\infty \}$ of the solutions of nonlinear differential equations involved in quantum electrodynamics.
