Exclusions
Description
This module covers those elements of Complex Variable Theory that form part of the toolbox of a theoretical physicist. This includes analytic functions, Cauchy-Riemann equations, Taylor's Theorem, simple convergence tests, non-analyticity, simple and multiple poles, Laurent series, convergence and simple analytical continuation, residues and their calculation, branch points, cuts and more on analytic continuation, Cauchy's theorem and Cauchy's integral formulae, residue theorem and lots of applications including integrands with cuts.
Learning Outcomes
By the end of the module the student should be able to:Determine whether a complex function is analytic and identify its singular points;Evaluate Taylor and Laurent series of complex valued functions and make elementary checks on their convergence properties;Determine and identify poles of complex valued functions;Apply Cauchy's integral formula and the Residue Theorem to evaluate integrals;Understand and use the concepts of branch points and cuts, particularly in the context of contour integration integrals;Explore this topic beyond the taught syllabus.
