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?

Suppose that a function f z is continuous in a domain D. For it must be analytic in a neighborhood of z 0 Sec. The branch is not defined on the segment P2 P1.

Each point on this circle is mapped onto itself. With the aid of the corollary in Sec. Chapter 1. The proof is now complete. Thus f is a real-valued function of a complex variable. The domains most frequently encountered in the applications are simply connected; and, since a function that is harmonic in a simply connected domain always has a harmonic conjugate Sec. This is shown in the next section, where the logarithmic function is developed, and is illustrated in the following example. Then solve for q z. We now illustrate how these observations can be used to establish the images of certain regions. It is, in fact, possible to change the interval over which the parameter ranges to any CHAP. Returning to the verification of the statement in italics just above, we observe that if x and y satisfy equation 4 , we can use relations 2 to substitute for those variables. To prove this remarkable theorem, we assume that a function f is analytic at a point z 0. The special case in which C is a simple closed polygon is proved on pp. It can be useful in locating regions of the complex plane in which a given analytic function has zeros.

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

It is one of the easier complex analysis books to work through, and a good place to start. A large region may, however, be transformed into a region that bears no resemblance to the original one. Apply inequality 1 , Sec. Another, strictly algebraic, derivation is given in Exercise 15, Sec. We need, however, some preliminary results regarding zeros of analytic functions. Shopbop Designer Fashion Brands. Singular points will play an important role in our development of complex analysis in chapters to follow. There are a number of other important properties of e z that are expected. Give an alternative proof based on the corresponding result for real numbers and using identity 8 , Sec. If the values of the function are prescribed along the boundary, the problem is known as a boundary value problem of the first kind, or a Dirichlet problem. Suggestion: In each part of this exercise, use the corresponding property of integrals of real-valued functions of t, which is graphically evident. Why is the function sinh e z entire? This can be seen by following the same general procedure that was used in Sec.
