This CBMS Conference "Nonlocal Dynamics--Theory, Computation and Applications" is to be held at Illinois Institute of Technology, Chicago, during June 4-9, 2017. Various complex systems in engineering and science are under long range or nonlocal interactions. There is a growing recognition of a role for including nonlocal effects in better modeling these systems. As a result, nonlocal partial differential equations are appropriate mathematical models for certain optimal control systems, dislocation dynamics in crystals, porous media flows, anomalous dffusion of particles in fluids, and many other systems. Nonlocal effects and long range diffusion also occur in the cell density evolution in certain biological processes, such as embryological development. In order to better understand nonlocal engineering and scientific systems, we must understand the properties of nonlocal equations. This conference brings a top mathematician as the principal lecturer, together with experts and newcomers from relevant mathematical and scientific communities, to learn, examine and investigate theoretical and computational issues in this subject. Nonlocal partial differential equations are macroscopic models for complex systems under long range interactions. They have led to many mathematically challenging questions at the interface of analysis, computation, stochastic analysis and partial differential equations. To realize the full power of nonlocal equations as mathematical models for complex systems, analysis and numerical approximations are crucial. This conference aims to summarize the past achievements in this subject, and discuss future research directions. It further stimulates research in the development of analytical, dynamical and computational tools for nonlocal models and their applications. The Principal Lecturer for this conference is Professor Qiang Du at Columbia University. The conference consists of ten lectures by Qiang Du, together with supplemental presentations by a few experts, round table discussions, and a session on open problems. The participants include graduate students, postdocs, junior researchers and experts from regional and other institutions.

本次CBMS会议“非局部动力学——理论、计算和应用”将于2017年6月4日至9日在芝加哥伊利诺伊理工学院举行。工程和科学中的各种复杂系统都处于远距离或非局部相互作用下。越来越多的人认识到，在更好地为这些系统建模时，包括非局部效应的作用。因此，非局部偏微分方程是某些最优控制系统、晶体中的位错动力学、多孔介质流动、流体中颗粒的异常扩散以及许多其他系统的合适数学模型。在胚胎发育等生物过程中，细胞密度的演化也会发生非局部效应和长距离扩散。为了更好地理解非局部工程和科学系统，我们必须了解非局部方程的性质。本次会议邀请了一位顶级数学家作为首席讲师，与相关数学和科学界的专家和新人一起学习，检查和研究这一主题的理论和计算问题。非局部偏微分方程是复杂系统在长范围相互作用下的宏观模型。它们在分析、计算、随机分析和偏微分方程的界面上引发了许多具有数学挑战性的问题。为了实现非局部方程作为复杂系统数学模型的全部功能，分析和数值近似是至关重要的。本次会议旨在总结该学科过去的研究成果，并讨论未来的研究方向。它进一步刺激了非局部模型及其应用的分析、动态和计算工具的发展研究。本次会议的首席讲师是哥伦比亚大学的杜强教授。会议包括杜强的十场演讲，几位专家的补充报告，圆桌讨论和一个公开问题的会议。参与者包括来自地区和其他机构的研究生、博士后、初级研究人员和专家。欲了解更多信息，请访问会议网页：www.math.iit.edu/nonlocaldynamics.html。
