On the rational cuspidal subgroup and the rational torsion points of Jo(pq)
For two distinct prime numbers p, q, we compute the rational cuspidal subgroup C(pq) of J0(pq) and determine the l-primary part of the rational torsion subgroup of the old subvariety of J0(pq) for most primes l.Some results of Berkoviˇc on the nontriviality of the Mordell-Weil group of some Eisen...

| Summary: | For two distinct prime numbers p, q, we compute the rational
cuspidal subgroup C(pq) of J0(pq) and determine the l-primary part of the rational torsion subgroup of the old subvariety of J0(pq) for most primes l.Some results of Berkoviˇc on the nontriviality of the Mordell-Weil group of some Eisenstein factors of J0(pq) are also refined. |
