INSTRUCTOR:   Charles Conley,  GAB 475,  (940) 565-3326

OFFICE HOURS:   Tuesday and Thursday, 1:30-3:30 and by appointment

CLASS MEETS:   TR 3:30-4:50, GAB 201

EXAMS, HOMEWORK, AND GRADING: There will be two 100 point midterms, on Tuesday, Oct. 9 and Tuesday, Nov. 13, and a comprehensive 180 point final, on Thursday, Dec. 13, 1:30-3:30.  There will also be twelve 10 point homeworks, due Thursdays at the beginning of class.  There will be no make-up exams except for emergencies, and late homework will be worth half-credit.

TEXT, PREREQUISITES, AND OTHER REFERENCES: The text is Complex Analysis for Mathematics and Engineering (fourth edition), by Mathews and Howell.  The prerequisites are Math 1710-20 and 2730, the calculus sequence.

TOPICS:   We will begin by going over multiplication of complex numbers in rectangular and polar coordinates.  Then we will study differentiability of functions of one complex variable, followed by Taylor and Laurent series and contour integration.  We will also discuss conformal maps and Julia and Mandelbrot sets if time permits.  We will give some rigorous proofs, but no prior exposure to proofs will be assumed.  Concrete examples and calculations will be emphasized.

Chapters 1-2:  Complex numbers and functions.

Chapters 3-5:  Analytic and harmonic functions, power series functions, and the elementary functions such as e^z.

Chapters 6-8:  Complex integration, contour integration, and Taylor and Laurent series.  These chapters contain many surprising and beautiful theorems, and comprise the centerpiece of the course.
