A 6-month research-intensive program titled "Dispersive hydrodynamics: mathematics, simulations and experiments, with applications in nonlinear waves" will be held at the Isaac Newton Institute, University of Cambridge, UK from July 6–December 18, 2020. Dispersive hydrodynamics is an emergent mathematical field of research focusing on dynamic and stochastic, multiscale wave phenomena described by nonlinear partial differential equations that physically encompass the complex interplay between long-scale, hydrodynamic, and short-scale, dispersive, effects. Building upon at least six dedicated workshops and numerous conference minisymposia on the subject since 2012, this will be the first extended program on dispersive hydrodynamics. It will attract at least 25 long-term, residential visitors at any given time and 40 or more participants in each of 5 week-long workshops. The diverse, international roster of participants includes leading researchers in the applied mathematical sciences. This National Science Foundation award provides travel support for early career applied mathematicians from the United States to participate in the workshops and the long-term program. Traditionally underrepresented groups in applied mathematics will be encouraged to apply. This support enables sustained opportunities to interact with leading researchers from across the world. Such interactions and contacts are invaluable to beginning researchers, both to inspire research, and for professional development, thereby helping to cultivate the very best young researchers. These researchers will be the next generation of applied mathematicians who advance this and other applied mathematical fields of research. Dispersive hydrodynamics has emerged as a unified mathematical framework for the description of multiscale nonlinear wave phenomena in dispersive media, encompassing both dynamic and stochastic aspects of wave propagation. Theoretical and experimental developments have spawned new areas of applied mathematical research. The mathematical program weaves together research topics on integrable and nonintegrable dispersive PDEs, convex and nonconvex dispersive hydrodynamic systems, multidimensional waves, asymptotic analysis, numerical analysis, randomness and turbulence in nonlinear dispersive waves. Applications include fluid mechanics and go well beyond, to nonlinear optics, superfluids (Bose-Einstein condensates), condensed matter, and granular crystals. The program website can be found at http://www.newton.ac.uk/event/hyd, with links to the workshops and other activities.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.

一项为期6个月的研究密集项目将于2020年7月6日至12月18日在英国剑桥大学艾萨克·牛顿研究所举行，该项目名为《弥散流体动力学：数学、模拟和实验及其在非线性海浪中的应用》。弥散流体动力学是一个新兴的数学研究领域，主要研究由非线性偏微分方程组描述的动态和随机的多尺度波动现象，它物理上包含了长尺度、流体动力学和短尺度、色散效应之间的复杂相互作用。自2012年以来，在至少六个专门的研讨会和许多关于该主题的小型会议的基础上，这将是关于弥散流体动力学的第一个扩展方案。它将在任何给定的时间吸引至少25名长期居住的参观者，并在为期5周的研讨会中每一次吸引40人或更多的参与者。学员名单多样化，包括应用数学科学领域的顶尖研究人员。这项国家科学基金会奖为来自美国的早期职业应用数学家参加研讨会和长期计划提供旅行支持。传统上在应用数学领域代表性不足的群体将被鼓励申请。这种支持使我们有机会与来自世界各地的顶尖研究人员互动。这种互动和接触对于初级研究人员来说是非常宝贵的，既可以激励研究，也可以促进专业发展，从而有助于培养最优秀的年轻研究人员。这些研究人员将是下一代应用数学家，他们将推动这一领域和其他应用数学领域的研究。色散流体动力学已成为描述色散介质中多尺度非线性波动现象的统一数学框架，它涵盖了波传播的动态和随机两个方面。理论和实验的发展催生了应用数学研究的新领域。该数学程序将可积和不可积色散偏微分方程组、凸和非凸色散流体动力系统、多维波动、渐近分析、数值分析、非线性色散波中的随机性和湍流等研究课题编织在一起。应用包括流体力学，远远超出了非线性光学、超流体(玻色-爱因斯坦凝聚体)、凝聚态物质和颗粒晶体。该计划的网站可以在http://www.newton.ac.uk/event/hyd，上找到，其中有研讨会和其他活动的链接。这一奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
