On the cyclicity of the group of Fp-rational points of non-CM elliptic curves

چکیده
ABSTRACT: Let E be an elliptic curve defined over Q and without complex multiplication. For a prime p of good reduction, let E be the reduction of E modulo p. Assuming that certain Dedekind zeta functions have no zeros in Re(s) > 3/4, we determine how often E(Fp) is a cyclic group. This result was previously obtained by J. -P. Serre using the full Generalized Riemann Hypothesis for the same Dedekind zeta functions considered by us.

On the elliptic curves of the form $ y^2=x^3-3px $
By the Mordell-Weil theorem, the group of rational points on an elliptic curve over a number field is a finitely generated abelian group. There is no known algorithm for finding the rank of this group. This paper computes the rank of the family $ E_p:y^2=x^3-3px $ of elliptic curves, where p is a prime.
متن کاملEfficient elliptic curve cryptosystems
Elliptic curve cryptosystems (ECC) are new generations of public key cryptosystems that have a smaller key size for the same level of security. The exponentiation on elliptic curve is the most important operation in ECC, so when the ECC is put into practice, the major problem is how to enhance the speed of the exponentiation. It is thus of great interest to develop algorithms for exponentiation...
متن کاملOn the Elliptic Curves of the Form $y^2 = x^3 − pqx$
By the Mordell- Weil theorem, the group of rational points on an elliptic curve over a number field is a finitely generated abelian group. This paper studies the rank of the family Epq:y2=x3-pqx of elliptic curves, where p and q are distinct primes. We give infinite families of elliptic curves of the form y2=x3-pqx with rank two, three and four, assuming a conjecture of Schinzel ...
متن کاملComplete characterization of the Mordell-Weil group of some families of elliptic curves
The Mordell-Weil theorem states that the group of rational points on an elliptic curve over the rational numbers is a finitely generated abelian group. In our previous paper, H. Daghigh, and S. Didari, On the elliptic curves of the form $ y^2=x^3-3px$, Bull. Iranian Math. Soc. 40 (2014), no. 5, 1119--1133., using Selmer groups, we have shown that for a prime $p...
متن کاملThe Elliptic Curves y 2 = x 3 − t 2 x over F p
Let p be a prime number, Fp be a finite field and t ∈ Fp = Fp − {0}. In this paper we obtain some properties of elliptic curves Ep,t : y = y = x − tx over Fp. In the first section we give some notations and preliminaries from elliptic curves. In the second section we consider the rational points (x, y) on Ep,t. We give a formula for the number of rational points on Ep,t over Fp for an integer n...
