paper on orders instead of rings of integers

[William Stein]

Hi Math 581f.,

There is a beautiful paper on orders that avoids the hypothesis that
the order be maximal here:

Since several of you in class are doing projects that somehow involve
non-maximal orders,
I highly recommend you take a look!
