Complex Integrations,s and have far-ranging applications. Notice that many important properties of analytic functions are very difficult to prove without use of complex integrations. For instance, the existence of higher derivatives of analytic functions is a striking property of this type. There occur real integrals in大吃大喝 发表于 2025-3-27 05:00:53
Calculus of Residues and Applications to Contour Integration,., except for . inside .. If . has a removable singularity at ., then it is clear that the integral will be zero. If . is a pole or an essential singularity, then the answer is not always zero, but can be found with little difficulty. In this chapter, we show the very surprising fact that Cauchy’s rPtsd429 发表于 2025-3-27 07:11:47
Bilinear Transformations and Applications, which we shall answer more abstract questions for determining whether and in what manner a given finite portion of an analytic surface could be represented on a portion of a plane. This chapter also deals with fixed points of bilinear transformations, elliptic, hyperbolic, and parabolic transformat描述 发表于 2025-3-27 12:27:09
