DOI: 10.1080/00295639.2024.2303107

Abstract: Abstract The second-moment (SM) method is a linear variant of the quasi-diffusion (QD) method for accelerating the iterative convergence of Sn source calculations. It has several significant advantages relative to the QD method, diffusion synthetic… read more here.

DOI: 10.1098/rsos.170390

Abstract: We consider the problem of finding the spectrum of an operator taking the form of a low-rank (rank one or two) non-normal perturbation of a well-understood operator, motivated by a number of problems of applied… read more here.
