报告题目：Multi-fidelity method for a class of kinetic models with uncertainties

报告摘要：

(1) In this talk, we will discuss some recent development on the multi-fidelity methods for solving a class of kinetic equations with multi-dimensional random inputs and different scalings. The multiscale Boltzmann equation, linear transport equation and epidemic transport system will be particularly studied. This is joint work with Giulia Bertaglia, Lorenzo Pareschi and Xueyu Zhu.

(2) We will focus essentially on two classes of strategies: multi-fidelity control variates methods and bi-fidelity stochastic collocation methods. The various approaches considered are analyzed in light of the different surrogate models used and the different numerical techniques adopted. Given the relevance of the specific choice of the surrogate model, an application-oriented approach has been chosen in the presentation.
