Capturing the Macroscale Behavior with the Help of Microscale Models

Speaker: Prof. Weinan E., Princeton University

I will try to give a candid assessment of the current status of the field, discussing both the main successes and the major difficulties. I will start by reviewing some of the classical methodologies. I will then discuss the attempts that have been made to construct general frameworks. I will present a relatively new strategy for constructing seamless techniques that do not require going back and forth between the macro and micro states of the system.
If time permits, I will also discuss some typical instabilities and inconsistencies that can arise in multiscale methods.
