## Abstract We study the set __S__ = {(__a, b__) ∈ __A__ Γ— __A__ : __aba__ = __a, bab__ = __b__} which pairs the relatively regular elements of a Banach algebra __A__ with their pseudoinverses, and prove that it is an analytic submanifold of __A Γ— A__. If __A__ is a C\*‐algebra, inside __S__ lies a
