Anderson acceleration is an optimisation technique designed to improve the convergence of fixed-point iterations, a common approach utilised in solving nonlinear equations. By blending current and ...
Given a sequence $\{x_n\}^\infty_{n=0}$ in a Banach space, it is well known that if there is a sequence $\{t_n\}^\infty_{n=0}$ such that $\|x_{n+1} - x_n\| \leqslant ...
SIAM Journal on Numerical Analysis, Vol. 54, No. 5 (2016), pp. 2750-2774 (25 pages) We consider robust iterative methods for discontinuous Galerkin (DG) H(div, Ω)-conforming discretizations of the ...
