In this note, we present results on extrapolated iterative methods, especially the extrapolated successive overrelaxation (ESOR). We show that they converge even if the original iteration diverges ...
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 ...
General aspects of polynomial interpolation theory. Formulations in different basis, e.g. Lagrange, Newton etc. and their approximation and computational properties ...
