Accelerated spectral refinement Part I: simple eigenvalue
The Journal of the Australian Mathematical Society Series B Applied Mathematics
A general framework is developed for constructing higher order spectral refinement schemes for a simple eigenvalue. Well-known techniques for ordinary spectral refinement are carried over to higher order spectral refinement yielding faster rates of convergence. Numerical examples are given by considering an integral operator.doi:10.1017/s0334270000011784 fatcat:btbq7llazbd7ri7up2qybfauou
