Homework: (suggested problems)

Assignments are not to be turned in. "due" means the date solutions will be posted online in WebCT
. The idea is to give you time to think about the problems without the temptation of looking at the solutions.

Topics covered in Class:

  • 10/17: Multiplicative functions, 7.2, definition of perfect numbers from 7.3

    Curiosities: Here you can find information about multiplicative functions. In particular, there are tons of examples!

  • Other Resources:

    In no particular order! I'll keep updating this, so let me know of any suggestions!
    • A proof of Bertrand's postulate by Erdos.
    • Zeta Grid, a project to find zeros of the Riemann ζ-function. (Thanks Tim for the suggestion.)
    • The Euler phi function.
