“…The radiative transport model plays an important role in quantitative modeling and analysis of particle transport processes in many physical and biological applications such as astrophysics [5,19], nuclear engineering [23,30], biomedical optics [1,2,25,33,41], radiation therapy [20,37]. In this paper, we consider the numerical solution to the timedependent radiative transport equation (RTE) with isotropic scattering kernel:…”
