I have used * to mark those that introduce standard numerical methods,
@looks like it might  be tricky, but very interesting.
There is a large collection around Peano-Picard. There are some that introduce
comparison, others that look like they use Arzela-Ascoli. You should choose
a good sample rather than doing all those that focus on one single issue (and leaving
the rest). #11 and 12 are an absolute must!
