Syllabus
See online syllabus at MATH
6321. We will coverthe first six chapter of the texbook. This
will leave us sometime
at the end of the course for topic that may be of intewrest 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. 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,
35% midterms and 50% final.
