“…The intersection number, like our height pairing, is expressed as a sum of local terms (which are calculated, in both cases, by counting representations by quadratic forms). This fact actually permits one to deduce our theorem from the results of [10] in some special cases, e.g., in the first non-trivial case N = 37 [23].
