Number theory notes

Back to work on this paper, I’m looking through an intro to number theory to find any helpful ideas.

Random notes

One notational convention I didn’t know was that if \frac{a}{b} is an integer, then we write “b divides a” as b|a.  If this is not the case and “b does not divide a” then we write b \dagger a.  In the paper I’m working on I use the coprime notation of a \bot b.

Fermat’s little theorem – if p is prime then p | n^p-n

Wilson’s theorem – if p is prime then p|[(p-1)! + 1]
