Monday's lecture (October 23)

[Ken Ribet]

Dear Math 115,

I'm keen to give you a proof of quadratic reciprocity other than the
one that's in our book (i.e., other than the one that I sketched on
Friday). I've decided to offer an explanation of an interesting proof
that was published in 1991 by G. Rousseau. You can look at it in
advance by going to

Best,
Ken R
