Formal Solutions for Polarized Radiative Transfer. I. The DELO Family
摘要：
关于偏振辐射转移方程的数值积分问题的讨论尚处于开放状态，过去不同作者提出的不同数值格式之间的比较也不完全清楚。为了便于理解不同的形式求解器的优点和缺点，这项工作提出了一个参考范例，他们的表征的准确性，稳定性和计算成本的概念的基础上。特别注意了解属于对角元素λ算子家族的数值方法，试图突出其特异性。
英文摘要：
The discussion regarding the numerical integration of the polarized radiative transfer equation is still open and the comparison between the different numerical schemes proposed by different authors in the past is not fully clear. Aiming at facilitating the comprehension of the advantages and drawbacks of the different formal solvers, this work presents a reference paradigm for their characterization based on the concepts of order of accuracy, stability, and computational cost. Special attention is paid to understand the numerical methods belonging to the Diagonal Element Lambda Operator family, in an attempt to highlight their specificities.
