Syllabus
See online syllabus at MATH
6321. We will cover the first six chapter of the texbook. This
will leave us sometime at the end of the course for topic that may be of interest to the
students.
Prerequisite
MATH 4317, 4320
Textbook
John B. Conway, "Functions of one complex variables I", Springer, 2nd
Edition.
Grading
I will collect HW every 2 weeks for a total of 5/6 HW. On top there
will be two in class midterms and a in class final. he first midterm
is tentatively scheduled for Thursday February 21 and the
second on Thursday March 28. Midterms and final
will be cumulative. The possibility of personal project will be
discussed later during the class. The grading scheme will be 15% HW,
40% midterms and 45% final.
