MA30345: Complex analysis

[Page last updated: 22 May 2025]

Academic Year: 2025/26
Owning Department/School: Department of Mathematical Sciences
Credits: 6 [equivalent to 12 CATS credits]
Notional Study Hours: 120
Level: Honours (FHEQ level 6)
Period:
Semester 2
Assessment Summary: EXCB 100%
Assessment Detail:
  • MA32045 Examination (EXCB 100%)

Like-for-like reassessment (where allowed by programme regulations)
Requisites: In taking this module you cannot take MA20219
Before taking this module you must ( take MA12003 AND take MA12004 ) OR take MA12011 OR ( take AT LEAST 1 MODULE FROM {MA10207, MA10274} AND take MA10236 )
Learning Outcomes: By the end of the unit, you should be able to:
  • demonstrate a good knowledge and understanding of the principal tools of complex analysis;
  • calculate and justify complex derivatives, contour integrals, power series, and Laurent series;
  • apply the theory to simple examples.



Synopsis: You will study functions of complex (as opposed to real) variables. These functions have surprising and often beautiful properties; for example, a striking result is the following: the definition of the derivative of a function of a complex variable is the same as the one for functions of a real variable (which you encountered in Year 1); however, if a function of a complex variable is once differentiable, then it is actually infinitely differentiable (which is not the case for real functions).

Content: The complex plane. Functions of a complex variable. Continuity, complex derivative. Contour integrals. The Cauchy-Riemann equations. Cauchy's theorem. Cauchy integral formulae. Power series and analytic functions. Liouville's theorem. Isolated zeroes. Laurent expansions. Isolated singularities. Cauchy's residue theorem. Applications to real definite integrals.
