This award provides participant support to the North American High Order Methods Conference (NAHOMCon), to be held June 2-5, 2019 at the San Diego State University. The conference will serve as a forum for computational scientists, mathematicians, scientists and engineers to share ideas and techniques on and further the state of the art of advanced high order methods used to solve a broad range of scientific and engineering problems. American competitiveness depends heavily on technological advances.Yet American research on high order methods has been at a disadvantage compared to that in European or other nations due to the lack of conferences devoted to the subject. This conference will have broad impacts by providing a forum for researchers on high order numerical methods for the solution of scientific and engineering problems of strategic importance. It also recognizes the need for younger researchers, women and minorities to have a forum in the US. More details about the conference can be found at https://www.nahomcon19.sdsu.edu/.High order approximations to PDEs, be they finite difference, finite element or spectral, have needed advantages over lower order methods. Of course, they have lower errors for a given number of degrees of freedom. But also they are usually designed to have lower dissipation and dispersion errors. Their high resolution makes them more suitable for intrinsic multiscale problems such as turbulence computations, chemically reacting flows and nuclear fusion reaction. The NSF currently supports numerous research projects on high order methods, but no nationwide conferences are in place that are focused on their study. The proposed conference topics are based on the general thrusts of these projects and are the forefront of high order method development. They include provably stable schemes, fast solvers for high order methods, methods for complex geometries, efficient and parallel implementations. Applications are considered in a range of fields including geoscience, fluid mechanics, combustion, solid mechanics, electromagnetics, biomedical, and image processing.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项为将于2019年6月2日至5日在圣地亚哥州立大学举行的北美高阶方法会议（NAHOMCon）提供参与者支持。会议将作为计算科学家，数学家，科学家和工程师的论坛，分享思想和技术，并进一步发展用于解决广泛科学和工程问题的先进高阶方法的最新技术。美国的竞争力在很大程度上依赖于技术的进步，但由于缺乏专门的会议，美国在高阶方法方面的研究与欧洲或其他国家相比一直处于劣势。本次会议将通过为研究人员提供一个论坛，为解决具有战略重要性的科学和工程问题提供高阶数值方法，从而产生广泛的影响。它还认识到年轻研究人员、女性和少数族裔需要在美国举办论坛。有关会议的更多详细信息，请访问https://www.nahomcon19.sdsu.edu/.High偏微分方程的阶次逼近，无论是有限差分、有限元还是谱，都比低阶方法具有优势。当然，对于给定的自由度，它们具有较低的误差。而且它们通常被设计成具有较低的耗散和色散误差。它们的高分辨率使其更适合于本征多尺度问题，如湍流计算，化学反应流和核聚变反应。美国国家科学基金会目前支持许多高阶方法的研究项目，但没有全国性的会议是集中在他们的研究。建议的会议主题是基于这些项目的一般推力，是高阶方法发展的最前沿。它们包括可证明稳定的计划，快速求解高阶方法，复杂几何形状的方法，高效和并行实现。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
