Shalom Lee,
in page 1-1, 1-2, 1-5 - mainly a matter of notation and being consistent with the class, the index of R/r should start from t and not from t + 1
in page 1-3, last equation at the bottom, in the second expression there is i believe a missing gamma
1-4, 1-5, perhaps it's worth mentioning as a footnote or something… V(lambda, t) is the same as G (lambda, t) (as presented in the first page) and V(n, t) is the same as G(n, t)
thanks
Rafi
