For shipments to locations outside of the U. All shipping options assume the product is available and that processing an order takes 24 to 48 hours prior to shipping. Pricing subject to change at any time. Complex Variables and Applications, 9e will serve, just as the earlier editions did, as a textbook for an 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. The text is designed to develop the theory that is prominent in applications of the subject. You will find a special emphasis given to the application of residues and conformal mappings. To accommodate the different calculus backgrounds of students, footnotes are given with references to other texts that contain proofs and discussions of the more delicate results in advanced calculus. Improvements in the text include extended explanations of theorems, greater detail in arguments, and the separation of topics into their own sections. Need support? We're here to help - Get real-world support and resources every step of the way.

The introduction to the concept of mapping in Chap. Also, it is not always convenient to use notation that distinguishes between a given function and its values.

Finally, since points on the x axis correspond to points on the u axis and since a linear fractional transformation is a one to one mapping of the extended plane onto the extended plane Sec. Show that the component function v x, y has maximum and minimum values in R which are reached on the boundary of R and never in the interior, where it is harmonic. Suppose that x, y is on the branch lying in the first quadrant. Corollary 2. Hence, according to the preceding lemma, f z has the constant value f z 0 throughout N0. This book is printed on acid-free paper. Condition 3 thus holds. By applying the extended form 3 , Sec. Suppose that a function f z is continuous in a domain D. Write a customer review. In all of our applications, both conditions a and b will be satisfied. We limit our attention to fairly simple examples and begin with a surface for log z. Statement 4 is, then, to be interpreted in the same way that statement 2 is. This method, stated just below as Theorem 2, is sometimes easier to use than the theorem in Sec.

We will keep fighting for all libraries - stand with us! Search the history of over billion web pages on the Internet.

But u cannot be a harmonic conjugate of v since, as verified in Exercise 2 b , Sec. In view of our corollary to Theorem 1, we now know that there is no larger circle about z 0 such that at each point z interior to it the Taylor series converges to f z. As defined on either sheet, the function is the analytic continuation, across the cut, of the function defined on the other sheet. Mardsen and Hoffman can also serve as a follow up, but if one works through Churchill, then Lang is very doable. To do this, we first show that the boundary of the strip is mapped in a one to one manner onto the real axis in the w plane, as indicated in Fig. It is analytic at a point z 0 if it is analytic in some neighborhood of z 0. Let z 0 be an isolated singular point of a function f. Suggestion: In each part of this exercise, use the corresponding property of integrals of real-valued functions of t, which is graphically evident. C and, since see Exercise 13, Sec. Suggestion: The most efficient way to find this transformation is to use equation 1 in Sec. While definition 2 provides a means of testing whether a given point w0 is a limit, it does not directly provide a method for determining that limit. The polygonal line Sec.
