NettetAnalytic Function Theory of Several Variables - Jan 18 2024 The purpose of this book is to present the classical analytic function theory of several variables as a standard subject in a course of mathematics after learning the elementary materials (sets, general topology, algebra, one complex variable). NettetThe feature of analytic functions that is used in the present chapter is that any analytic function can be represented by a power-series expansion. More precisely, suppose ais an analytic function of the complex variable z= x+ iyin a domain Dof the complex plane, and let z 1 be any point of D. Then a(z) = X1 k=0 a k(z z 1) k; (4.3)
NettetAnalytic functions also arise when one solves differential equations. Even equations with constant coefficients, like y′′+y = 3 0, can give rise to transcendental functions such as sin(z), cos(z) and ez. A special case of course is integration. NettetThe gamma function then is defined as the analytic continuation of this integral function to a meromorphic function that is holomorphic in the whole complex plane except zero and the negative integers, where the …
