Introduction to number theory lecture 50. Dirichlet characters

[@ethanjahan780]

In the beginning of the lecture he meant that Xi(m) = 0 if m and n are NOT coprime

Thank you for clarifying!

If m and N are not coprime then m is not gonna be a unit anyways, so I don't understand why this needs to be specified.

That's because normally (wikipedia for example) Dirichlet characters are defined on all of Z
