Operator perturbation methods: a synthesis.
Abstract
This paper shows the equivalence of the perturbation methods decribed by Cannon, Scharmer, and Nordlund with a method based on the expansion of an inverse operator, discusses the treatment of non-linearities in the transfer equation, sketches an integral equation method for solving partial redistribution problems, and shows how the source function equation in a moving medium is modified. It also considers the impact of operator perturbation on methods for building model atmospheres and discusses the properties and construction of approximate integral operators.
