Speaker:     Prof. Lijian Jiang

Time:          Jun.16.2021 16:00-17:00

Location:    SIST 1A200

Host:            Prof. Yue Qiu

Abstract:

Multiscale phenomena significantly impact on the computation and modeling of scientific and engineering problems. In this talk, I will present the background, motivation, and ideas for multiscale model reduction.  Then I will introduce dynamic model decomposition and Koopman operator learning for nonlinear multiscale dynamic problems.
