Overview: This course is an introduction to the theory of complex valued functions, with equal emphasis given to the rigorous mathematical development of the subject as to practical applications of the theory.

 (1) Complex numbers and elementary functions (complex numbers, properties, stereographic projection, elementary functions, limits, continuity, differentiation)
(2) Analytic functions and integration (Cauchy-Riemann equations, multivalued functions, Riemann surfaces, integration, Cauchy's theorem, Cauchy's formula, generalizations, Liouville's theorem, Morera's theorem)
(3) Sequences, series and singularities (definitions, Taylor series, Laurent series, singularities, analytic continuation, infinite products)
(4) Residue calculus and applications (The residue theorem, definite integrals, principal-value integrals, integrals with branch points, the argument principle, Fourier and Laplace transforms)
(5) As time permits, a special topic chosen to suit class interest (possibilities: conformal mappings, asymptotic evaluation of integrals, elliptic functions, the prime number theorem, etc)
