The first objective of.the book is to develop those parts of the theory that areprominent in applications of the subject. The second objective is to furnish an intro-duction to applications of residues and conformal mapping. With regard to residues,special emphasis is given to their use in evaluating real improper integrals, findinginverse Laplace transforms, and locating zeros of functions. As for conformal map-ping, considerable attention is paid to its use in solving boundary value problemsthat arise in studies of heat conduction and fluid flow. Hence the book may beconsidered as a companion volume to the authors text "Fourier Series and Bound-ary Value Problems," where another classical method for solving boundary valueproblems in partial differential equations is developed.
The first nine chapters of this book have for many years formed the basis of athree-hour course given each term at The University of Michigan. The classes haveconsisted mainly of seniors and graduate students concentrating in mathematics,engineering, or one of the physical sciences. Before taking the course, the studentshave completed at least a three-term calculus sequence and a first course in ordinarydifferential equations. Much of the material in the book need not be covered in thelectures and can be left for self-study or used for reference. 前言/序言
This book is a revision of the seventh edition, which was published in 2004. Thatedition has served, just as the earlier ones did, as a textbook for a oneterm introductory course in the theory and application of functions of a complex variable.This new edition preserves the basic content and style of the earlier editions, thefirst two of which were written by the late Ruel V. Churchill alone.

好的,這是一份不涉及《復變函數及應用(英文版)(第8版)》內容的圖書簡介,字數控製在1500字左右。 --- 《經典力學導論:拉格朗日與哈密頓體係基礎》 作者: 約瑟夫·S·麥肯齊 (Joseph S. MacKenzie) 譯者: [此處可留空或填寫譯者姓名] 齣版社: 環球科學齣版社 齣版日期: 2023年10月 圖書簡介: 本書旨在為物理學、工程學及相關領域的本科高年級學生和研究生提供一個紮實、係統且富有洞察力的經典力學入門。它超越瞭牛頓力學的基本錶述,深入探討瞭更具普適性和優雅性的拉格朗日和哈密頓力學框架。作為一本現代經典力學教材,本書的獨特之處在於其對理論推導的嚴謹性與對物理圖像直觀理解的並重,尤其側重於如何利用這些先進的變分原理方法來解決復雜的動力學問題。 第一部分:從牛頓到拉格朗日——變分原理的基石 本書伊始,我們首先迴顧瞭牛頓力學的核心思想與局限性,為引入更宏大的理論框架奠定基礎。第一章著重介紹瞭約束係統的概念,並詳細闡述瞭虛擬位移和虛功原理,這是理解變分原理的關鍵跳闆。隨後,第二章係統地引入瞭歐拉-拉格朗日方程。我們不僅詳細推導瞭這一核心方程,還通過大量具體案例,如簡諧振子、係鏈和滾動的圓盤,展示瞭其在處理復雜約束問題時的巨大威力。本章特彆強調瞭守恒量的概念,以及諾特定理(Noether's Theorem)在理論物理中的深刻意義,盡管諾特定理的完整討論將在後續章節中深化。 第三章專注於守恒定律的深入探討。我們通過解析力學的視角,重新審視動量、角動量和能量的守恒,並探討瞭這些守恒量在約束係統下的錶現。本章引入瞭正則坐標和廣義動量,為過渡到哈密頓力學做好瞭準備。 第二部分:哈密頓力學的優雅結構 第四章是全書的轉摺點,聚焦於哈密頓力學的構建。我們從拉格朗日量齣發,通過勒讓德變換,係統地導齣瞭哈密頓量。本章詳細討論瞭哈密頓方程的結構,並闡明瞭哈密頓函數在相空間中的幾何意義。相空間的幾何描述,如相軌跡和相流的概念,被清晰地引入,幫助讀者建立起對動力學演化的直觀感受。 第五章深入探討瞭正則變換理論。我們介紹瞭一係列生成函數,並詳細推導瞭保持哈密頓方程形式不變的正則變換的條件。本章通過實例說明瞭如何利用正則變換簡化問題,例如如何通過選擇閤適的坐標係,將復雜的係統轉化為可積的簡單係統。泊鬆括號的概念也在本章中被引入,它不僅是檢驗正則性的工具,更是連接經典力學與量子力學的重要橋梁。 第六章將泊鬆括號的概念提升至更高維度。我們探討瞭泊鬆括號的代數性質,並展示瞭它如何優雅地描述物理量隨時間的演化。時間演化方程的泊鬆括號形式被清晰闡述,並與牛頓力學中的演化方程進行瞭對比,突顯瞭哈密頓形式的內在一緻性。 第三部分:進階主題與理論應用 第七章迴歸並強化瞭諾特定理的討論,將其置於哈密頓框架下進行考察。本章詳細證明瞭由對稱性(時間平移、空間平移和空間鏇轉)所産生的守恒量,是通過泊鬆括號的零值關係來體現的。這部分內容對於理解物理學中的基本守恒律至關重要。 第八章聚焦於可積性問題。我們引入瞭劉維爾-阿諾德(Liouville-Arnold)定理,探討瞭在有限自由度係統中,當存在足夠多相互獨立的守恒量時,係統軌綫可以被限製在環麵上的情況。本章提供瞭可積係統的經典例子,如三維諧振子,幫助讀者理解復雜係統的簡化可能性。 第九章將理論應用於波動與場論的邊緣。雖然本書主要集中於質點動力學,但本章簡要介紹瞭最小作用量原理在連續介質和經典場論中的推廣,例如彈性波的拉格朗日描述,為學生嚮更高級的場論學習做鋪墊。 第十章是對理論工具的綜閤應用與展望。本章通過一係列具有挑戰性的綜閤性習題和案例分析(如陀螺儀的進動、受迫振動的拉格朗日分析),鞏固讀者對前九章所學知識的掌握。最後,本書對經典力學與量子力學(特彆是薛定諤方程的經典極限)之間的深刻聯係進行瞭簡要而有力的展望。 本書特色: 1. 深度與廣度兼顧: 平衡瞭對變分原理的數學嚴謹推導與對物理圖像的清晰闡釋。 2. 強調結構美感: 特彆突齣瞭哈密頓力學的內在對稱性和泊鬆括號的代數結構。 3. 豐富的例題與習題: 每章末尾均附有難度分級的習題,旨在培養讀者利用高級框架解決實際問題的能力。 4. 現代視角: 將經典理論置於現代物理學的背景下進行審視,為進一步學習統計力學和量子場論打下堅實基礎。 《經典力學導論:拉格朗日與哈密頓體係基礎》不僅是一本教科書,更是一扇通往理論物理核心思想的門戶,它將引導讀者以一種更深刻、更優雅的方式理解物質世界的運動規律。
