Math 623: Complex Analysis

This is an introductory course in complex analysis, intended for advanced undergraduate and beginning graduate students.

Student Body:
Math, physics and eng majors. Graduate students in related areas
Background and Goals: 

This is an introduction to the theory of analytic functions of one complex variable. Attention is given to the techniques of complex analysis as well as the theory. It is highly recommended  for math majors and also suitable for students in the physical sciences and engineering.



Subsequent Courses: 

graduate courses

Course Content: 
  • The algebra of complex numbers; fractional powers.
  • Logarithm and power functions; exponential and trigonometric functions.
  • Analyticity; Cauchy-Riemann equations.
  • Integrals and Cauchy's Theorem and Formula
  • Morera's theorem; maximum modulus theorem; Liouville's theorem; Fundamental Theorem of Algebra.
