摘要
<jats:p> This article is concerned with the GW method for finite electronic systems. In the first step, we provide a mathematical framework for the usual one-body operators that appear naturally in many-body perturbation theory. We then give a rigorous mathematical formulation of the [Formula: see text] equations, and study the well-posedness of these equations, proving the existence of a unique solution in a perturbative regime. </jats:p>
