  • Numbers in italics represent problems that definitely satisfy that specification. 3:4 means problem 4 from homework 3. 2:1.4.8 means Abbott's exercise 8 from chapter 1.4, which was assigned on homework 2.
  • formulate and prove means you must come up with the statement of the theorem, in addition to proving it.
  • use means to use the result in question in the course of a proof
  • a named theorem is one with a person's name attached (such as the Bolzano-Weierstrass Theorem) or a phrase (such as the Mean Value Theorem)
  • a sequential characterization or a sequential criterion is a theorem of the form [statement not involving sequences] if and only if [statement involving sequences]. Examples include:
    • The sequential characterization of supremum.
    • The sequential criterion for continuity.
    • The sequential characterization of closed sets.
  • forms of completeness are: the Monotone Sequence Property, the Least Upper Bound Property, the Greatest Lower Bound Property, and the Bolzano-Weierstrass Property

Points can be earned by completing the following problems. Topology points may also be earned by using arguments that reference open, closed, and/or compact sets. Explanation points may also be earned by giving a very clear unsolicited explanation as part of one of your proofs.
