| Title | Rational Torsion in Elliptic Curves and the Cuspidal Subgroup |
| Authors | Amod Agashe; |
| Abstract |
Let A be an elliptic curve over ℚ of square free conductor N. We prove that if A has a rational torsion point of prime order r such that r does not divide 6N, then r divides the order of the cuspidal subgroup of J0(N). |
