MA465 COMPLEX VARIABLES (Cr. 3)

COURSE DESCRIPTION

Prerequisite:  MA 211 (Introduction to Matrix Theory and Linear Algebra) and MA 265 (Calculus III)

Offered:  On Demand

Course Description
Complex numbers, analytic functions, conformal mapping, residues and poles, analytic continuation, and Riemann surfaces.

Goal/Purpose
The purpose of this course is to apply the basic ideas of calculus (limits, differentiation, and integration) to functions of a complex variable.  These notions are studied from both a theoretical and an applied point of view.
