Let $q$ denote the fixed-point iteration process in Eq., and let $\Psi$ denote the Anderson-acceleration process in Eq., with asymptotic convergence factors $\rho_q$ and…

Let $q$ be a nonlinear fixed-point map with fixed point $x^*$, and consider the linearized fixed-point problem with matrix $I-q'(x^*)$. Suppose GMRES($\infty$) applied to this line…
