Title(1): Asymptotic preserving methods for kinetic equations

Abstract: Kinetic equations often contain multiple scales that lead to various asymptotic regimes, in which classical numerical methods become prohibitively expensive. Asymptotic-Preserving (AP) scheme is one efficient way to treat such multiscale problems. In this talk, I will explain the basic ideas in designing AP schemes and showcase a few examples in kinetic theory.

Title(2): Stability analysis for inverse multiscale kinetic equations

Abstract: In the inverse setting of kinetic theory, we consider recovering model coefficients from noisy boundary measurements. Then it raises the question of how the errors in the measurement affects the recovery. In this talk, we will discuss this issue and also explore its dependence on different scales.
