An Adaptive Angular Domain Compression Scheme For Solving Multiscale Radiative Transfer Equation

Autor: Song, Qinchen, Fu, Jingyi, Tang, Min, Zhang, Lei

When dealing with the steady-state multiscale radiative transfer equation (RTE) with heterogeneous coefficients, spatially localized low-rank structures are present in the angular space. This paper introduces an adaptive tailored finite point scheme

Confined run-and-tumble model with boundary aggregation: long time behavior and convergence to the confined Fokker-Planck model

Autor: Fu, Jingyi, Liang, Jiuyang, Perthame, Benoit, tang, Min

The motile micro-organisms such as E. coli, sperm, or some seaweed are usually modelled by self-propelled particles that move with the run-and-tumble process. Individual-based stochastic models are usually employed to model the aggregation phenomenon

A fast offline/online forward solver for stationary transport equation with multiple inflow boundary conditions and varying coefficients

Autor: Fu, Jingyi, Tang, Min

It is of great interest to solve the inverse problem of stationary radiative transport equation (RTE) in optical tomography. The standard way is to formulate the inverse problem into an optimization problem, but the bottleneck is that one has to solv
