By the end of the course the student should be able to: give an account of the concepts of analytic function and harmonic function and to explain the role of the Cauchy-Riemann equations. explain the concept of conformal mapping, describe its relation to analytic functions, and know the mapping properties of the elementary functions. describe the mapping properties of Möbius transformations and know how to use them for conformal mappings. define and evaluate complex contour integrals. give an account of and use the Cauchy integral theorem, the Cauchy integral formula and some of their consequences. analyze simple sequences and series of functions with respect to uniform convergence, describe the convergence properties of a power series, and determine the Taylor series or the Laurent series of an analytic function in a given region. give an account of the basic properties of singularities of analytic functions and be able to determine the order of zeros and poles, to compute residues and to evaluate integrals using residue techniques. use the theory, methods and techniques of the course to solve mathematical problems.
