Rational torsion in elliptic curves and the cuspidal subgroup
Amod Agashe
Let be an elliptic curve over $\Q$ of square free conductor . We prove that if has a rational torsion point of prime order such that does not divide , then $…
A visible factor for analytic rank one
Amod Agashe
Let be an optimal elliptic curve of conductor , such that the -function of vanishes to order one at . Let be a quadratic imaginary field in which all the pri…
Visibility and the Birch and Swinnerton-Dyer conjecture for analytic rank one
Amod Agashe
Let be an optimal elliptic curve over $\Q$ of conductor having analytic rank one, i.e., such that the -function of vanishes to order one at . Let b…
A visible factor of the special L-value
Amod Agashe
Let~ be a quotient of associated to a newform such that the special -value of (at ) is non-zero. We give a formula for the ratio of the special -valu…
