Local data of rational elliptic curves with nontrivial torsion

چکیده

By Mazur's Torsion Theorem, there are fourteen possibilities for the non-trivial torsion subgroup $T$ of a rational elliptic curve. For each $T$, such that $E$ may have additive reduction at prime $p$, we consider parameterized family $E_T$ curves with property they parameterize all $E/\mathbb{Q}$ which contain in their subgroup. Using these families, explicitly classify Kodaira-N\'{e}ron type, conductor exponent, and local Tamagawa number $p$ where has reduction. As consequence, find $2$-torsion or $3$-torsion point global $1$.

To appear in Acta Arithmetica. AVERAGE FROBENIUS DISTRIBUTIONS FOR ELLIPTIC CURVES WITH NONTRIVIAL RATIONAL TORSION

In this paper we consider the Lang-Trotter conjecture (Conjecture 1 below) for various families of elliptic curves with prescribed torsion structure. We prove that the Lang-Trotter conjecture holds in an average sense for these families of curves (see Theorem 3). Let E/Q denote an elliptic curve and let ∆E denote its discriminant. As usual, let ap(E) = p + 1 − #E(Fp). Then we have the following...

On computing rational torsion on elliptic curves

We introduce an l-adic algorithm to efficiently determine the group of rational torsion points on an elliptic curve. We also make a conjecture about the discriminant of the m-division polynomial of an elliptic curve.

Families of elliptic curves with rational 3-torsion

In this paper we look at three families of elliptic curves with rational 3-torsion over a finite field. These families include Hessian curves, twisted Hessian curves, and a new family we call generalized DIK curves. We find the number of Fq-isogeny classes of each family, as well as the number of Fq-isomorphism classes of the generalized DIK curves. We also include some formulas for efficient c...

On the torsion of rational elliptic curves over quartic fields

Let E be an elliptic curve defined over Q and let G = E(Q)tors be the associated torsion subgroup. We study, for a given G, which possible groups G ⊆ H could appear such that H = E(K)tors, for [K : Q] = 4 and H is one of the possible torsion structures that occur infinitely often as torsion structures of elliptic curves defined over quartic number fields. Let K be a number field, and let E be a...

Torsion of Rational Elliptic Curves over Cubic Fields

Let E be an elliptic curve defined over Q. We study the relationship between the torsion subgroup E(Q)tors and the torsion subgroup E(K)tors, where K is a cubic number field. In particular, we study the number of cubic number fields K such that E(Q)tors ̸= E(K)tors.
