Text(s): Most current editions of the following:Complex Variables and ApplicationsBy Brown, James and Churchill, Ruel (McGraw-Hill Publishing) RecommendedFundamentals of Complex AnalysisBy Saff, E.B., Snider, A.D. (Prentice Hall) Recommended Course Objectives To establish connections between real and complex variable analysis. To descrbe and explain procedural and conceptual aspects of basic complex analysis notions such as analytical functions, complex differentiation and integration, complex series, residues and poles. To master formal proofs of fundamental complex analysis results. To realize the significance of abstract complex analysis notions through applications to real world problems. Measurable Learning Outcomes: Find the modulus and the principle argument of a complex number. Analyze mapping properties of power, exponential and logarithmic functions. Compute limits and derivatives of functions of a complex variable. Demonstrate knowledge of the Cauchy-Riemann equations and their relations to differentiability of functions of a complex variable. Verify that a give function is analytic or harmonic. Define power, exponential, logarithmic and trigonometric functions of a complex variable. Define and evaluate contour integrals. Formulate and prove the Cauchy-Goursat theorem. Use the Cauchy integral formula to evaluate integrals along simple closed contours. State the maximum modulus principle. Obtain the Taylor and Maclaurin series representations of analytic functions. Find the Laurent series for functions of a complex variable. Define the residue and use it to evaluate integrals along simple closed contours. Use residues to compute improper integrals. Master the notions of linear and linear fractional transformations, and mappings of the upper half plane onto the open disk. Define the concept of a conformal mapping and relate it to harmonic functions.

NOTE: The intention of this master course syllabus is to provide an outline of the contents of this course, as specified by the faculty of Columbia College, regardless of who teaches the course, when it is taught, or where it is taught. Faculty members teaching this course for Columbia College are expected to facilitate learning pursuant to the course objectives and cover the subjects listed in the topical outline. However, instructors are also encouraged to cover additional topics of interest so long as those topics are relevant to the course's subject. The master syllabus is, therefore, prescriptive in nature but also allows for a diversity of individual approaches to course material.
