完全不同的物理、生物等現(xiàn)象常?梢杂孟嗨频奈⒎郑ɑ蚱渌┓匠堂枋鰹轭愃频臄(shù)學(xué)對(duì)象,這就是理論科學(xué)的美妙之處。在20世紀(jì),“振蕩理論”和后來(lái)的“波動(dòng)理論”作為統(tǒng)一的概念出現(xiàn)了,這意味著相似的方法和方程可以應(yīng)用于完全不同的物理問(wèn)題。在各種應(yīng)用中(很可能在大多數(shù)應(yīng)用中),振蕩過(guò)程的特征是其參數(shù)(如振幅和頻率)的緩慢變化(與特征周期相比)。波動(dòng)過(guò)程也是如此。
本書描述了與振蕩和慢變參數(shù)波有關(guān)的各種問(wèn)題。其中包括非線性和參數(shù)共振、自同步、衰減和放大孤子、自聚焦和自調(diào)制以及反應(yīng)擴(kuò)散系統(tǒng)。對(duì)于振蕩器,物理例子包括van der Pol振蕩器和鐘擺,它們是激光器的模型。對(duì)于波,例子來(lái)自海洋學(xué)、非線性光學(xué)、聲學(xué)和生物物理學(xué)。本書的最后一章描述了前面所有章節(jié)中考慮的振蕩器和波類的更形式化的漸近攝動(dòng)格式。
列夫·奧斯特洛夫斯基(Lev Ostrovsky),是科羅拉多大學(xué)博爾德分校應(yīng)用數(shù)學(xué)系兼職教授。他的研究興趣廣泛,包括非線性流體力學(xué)、非線性海洋學(xué)理論等。他曾獲得蘇聯(lián)國(guó)家獎(jiǎng)、俄羅斯科學(xué)院Mandelstam獎(jiǎng)、非線性科學(xué)與復(fù)雜性委員會(huì)Lagrange獎(jiǎng)和蘇聯(lián)發(fā)現(xiàn)獎(jiǎng)(Diploma),目前已出版了3本專著,發(fā)表了300多篇論文。
