complex numbers). Powers and roots of complex numbers. Planer sets (aspects of connectedness).
Functions of a complex variable: Limits and continuity. Differentiability and holomorphy. Cauchy-Riemann theory. Harmonic functions.
Elementary functions: Exponential, Trigonometric and hyperbolic functions. Logarithmic functions and Branch concepts. The inverses of such functions.
Complex integration: Contour (line) integrals. Cauchy’s theorem. Cauchy’s integral formula and its applications (such as: Maximum modulus principle, Mean value property (analytic and harmonic), Cauchy’s estimate, Liouville’s theorem, Fundamental theorem of algebra…).
Series representation for analytic functions: Sequences and infinite series. Taylor series. Power series and analyticity. Laurent series.
