摘要：
Noel Frederick Smyth（简称NFS）是澳大利亚数学学会会士、爱丁堡大学数学学院非线性波方向教授，于2023年2月5日逝世。NFS是从事非线性波理论研究的应用数学家中的杰出人物，研究领域覆盖广泛方向。在长达近四十年的学术生涯中，NFS提出的数学模型、学术思想与技术方法，对理解多种介质中的波动行为产生了重大影响。他的核心研究方向主要是孤立波（即孤子）与色散激波（又称波状水跃）在各类介质中的传播，涉及的介质包括光纤、液晶、浅水环境与大气。他提出的若干方法已被证明可有效分析相关波动现象的动力学与调制特性。本期《Wave Motion》（波动）期刊的致敬专文旨在简要介绍NFS的生平，梳理他的主要研究成就，展现他的科研能力、不懈的指导投入与坚定的奉献精神，同时分享他的往届学生、同事、好友与家人的追思。本文作者与NFS在个人与职业层面都有特殊联结，对他本人及其极具价值的研究工作怀有深切的感激之情。为表彰他在应用数学领域的成就，《Wave Motion》推出题为“Modelling Nonlinear Wave Phenomena: From Theory to Applications（非线性波现象建模：从理论到应用）”的特刊，呈现该领域的最新进展。
英文摘要：
Noel Frederick Smyth (NFS), a Fellow of the Australian Mathematical Society and a Professor of Nonlinear Waves in the School of Mathematics at the University of Edinburgh, passed away on February 5, 2023. NFS was a prominent figure among applied mathematicians who worked on nonlinear wave theory in a broad range of areas. Throughout his academic career, which spanned nearly forty years, NFS developed mathematical models, ideas, and techniques that have had a large impact on the understanding of wave motion in diverse media. His major research emphasis primarily involved the propagation of solitary waves, or solitons, and dispersive shock waves, or undular bores, in various media, including optical fibers, liquid crystals, shallow waters and atmosphere. Several approaches he developed have proven effective in analyzing the dynamics and modulations of related wave phenomena. This tribute in the journal of Wave Motion aims to provide a brief biographical sketch of NFS, discuss his major research achievements, showcase his scientific competence, untiring mentorship and unwavering dedication, as well as share final thoughts from his former students, colleagues, friends, and family. The authors had a special connection with NFS on both on personal and professional levels and hold deep gratitude for him and his invaluable work. In recognition of his achievements in applied mathematics, Wave Motion hosts a Special Issue entitled "Modelling Nonlinear Wave Phenomena: From Theory to Applications," which presents the recent advancements in this field.
