Format of the exam:
The exam will be a self-scheduled take-home exam. You are bound strictly by the honor code not to discuss any aspect of the exam with anyone after you have taken it. You have three hours to complete the exam. You may not use any books, notes, calculators, neighbors, computers, etc. In fact,
you may use nothing but a pencil, paper, and your brain.
Definitions you should be able to state:
1) Domain in C
2) Differentiable function f : S--> C
3) Analytic function
4) Holomorphic function
5) Open and closed set in C
6) Path connected set
7) Topologists' definition of continuity (prop. 2.4)
8) log, Log, Log_a, arg, arg_a, argument
9) Winding number of a path around a point.
10) Zero of order m
11) Isolated singularity
12) Removable singularity, pole, isolated essential singularity
13) Stereographic projection
14) Riemann sphere/extended complex plane
15) Behavior at infinity of f(z) (p. 207)
16) Meromorphic function
Theorems you should be able to state and prove:
1) The Paving lemma
2) Differentiation of power series
3) Cauchy Riemann equations
4) Partial converse to Cauchy Riemann equations
5) If |f| is constant on a domain D and f is differentiable then f is constant
6) Fundamental Theorem of contour integration

17 )Liouville's Theorem
18) Fundamental Theorem of Algebra
19) Identity Theorem (10.10 and 10.11)
20) Maximum Modulus Theorem
21) Minimum Modulus Theorem
22) Laurent's Theorem (including uniqueness)
23) Differentiation of negative power series lemma
24) Behavior at an isolated singularity (Lemma 11.2)
25) Behavior at a pole (prop. 11.4 and corollary 11.6)
