摘要

Nonlocality has become increasingly noticeable in nature. The interests in the effective modeling and the numerical simulation of its presence bring on new challenges to mathematicians. In this talk, we will discuss nonlocal models with a finite horizon of interactions and theirs roles in various applications. We will also reveal some practical risks due to inappropriately developed nonlocal models and numerical discretizations. We will show how systematic mathematical analysis can help making nonlocal modeling and simulations more effective and robust for problems in solid and fluid mechanics, autonomous vehicle traffic flows, and deep learning.
