Stressing motivation and technique, and containing a large number of problems and their solutions, this volume may be used as a text both in classrooms and for self-study. We don't offer credit or certification for using OCW. Topic 7: Taylor and Laurent series. This course provides an introduction to complex analysis which is the theory of complex functions of a complex variable. Unlike calculus using real variables, the mere existence of a complex derivative has strong implications for the properties of the function. 192 Pages. Da jede komplexe Zahl durch zwei reelle Zahlen in der Form + geschrieben werden kann, lässt sich eine allgemeine Form einer komplexen Funktion durch + ↦ (+) = (,) + (,) darstellen. Lecture Notes for Complex Analysis Frank Neubrander Fall 2003 Analysis does not owe its really signiﬁcant successes of the last century to any mysterious use of √ −1, but to the quite natural circumstance that one has inﬁnitely more freedom of mathematical movement if he lets quantities vary in a plane instead of only on a line. Most likely you have encountered this previously in 18.03 or elsewhere. Power series 1.9 1.5. Introduction i.1. Introduction. In this part of the course we discuss the arithmetic of complex numbers and why they are so important. Mathematik (Prüfungsversion ab WiSe 2015/16) Wahlpflichtmodule. This also has the (maybe disadvantageous) consequence that power series are introduced very late in the course.

Example 2.1. » students, complex analysis is their ﬁrst rigorous analysis (if not mathematics) class they take, and these notes reﬂect this very much. In that context, the complex numbers extend the number system from representing points on the x-axis into a larger system that represents points in the entire xy-plane. More specifically, the real numbers are simply numbers whose squares are non-negative. Holomorphic functions 1.1. Lie groups, discrete subgroups and homogeneous spaces (e.g. Let's see, standard stuff like Laurent series, complex numbers, Cauchy's theorem, Goursat on the way to Cauchy, Euler's formula etc. Complex analysis is a beautiful, tightly integrated subject. 4 1.

Since the course Analysis I (18.100B) is a prerequisite, topological notions like compactness, connectedness, and related properties of continuous functions are taken for granted. There are many complex variable books that are only a list of identities and integrals and I hate it. # $ % & ' * +,-In the rest of the chapter use.
