Non‐vanishing theorems for central L‐values of some elliptic curves with complex multiplication

open access: yesProceedings of the London Mathematical Society, Volume 121, Issue 6, Page 1531-1578, December 2020., 2020
Abstract The paper uses Iwasawa theory at the prime p=2 to prove non‐vanishing theorems for the value at s=1 of the complex L‐series of certain quadratic twists of the Gross family of elliptic curves with complex multiplication by the field K=Q(−q), where q is any prime ≡7mod8.

L‐equivalence for degree five elliptic curves, elliptic fibrations and K3 surfaces

open access: yesBulletin of the London Mathematical Society, Volume 52, Issue 2, Page 395-409, April 2020., 2020
Abstract We construct non‐trivial L‐equivalence between curves of genus one and degree five, and between elliptic surfaces of multisection index five. These results give the first examples of L‐equivalence for curves (necessarily over non‐algebraically closed fields) and provide a new bit of evidence for the conjectural relationship between L ...

Groups of generalized G‐type and applications to torsion subgroups of rational elliptic curves over infinite extensions of Q

open access: yesTransactions of the London Mathematical Society, Volume 6, Issue 1, Page 22-52, December 2019., 2019
Abstract Recently, there has been much interest in studying the torsion subgroups of elliptic curves base‐extended to infinite extensions of Q. In this paper, given a finite group G, we study what happens with the torsion of an elliptic curve E over Q when changing base to the compositum of all number fields with Galois group G.

Tate module and bad reduction [PDF]

open access: yes, 2020
Let C/K be a curve over a local field. We study the natural semilinear action of Galois on the minimal regular model of C over a field F where it becomes semistable.

On the distribution of Atkin and Elkies primes for reductions of elliptic curves on average [PDF]

open access: yes, 2015
For an elliptic curve E/Q without complex multiplication we study the distribution of Atkin and Elkies primes l, on average, over all good reductions of E modulo primes p.

AN IDENTITY-BASED ENCRYPTION SCHEME USING ISOGENY OF ELLIPTIC CURVES [PDF]

open access: yes, 2021
Identity-Based Encryption is a public key cryptosystem that uses the receiver identifier information such as email address, IP address, name and etc, to compute a public and a private key in a cryptosystem and encrypt a message.

Supercongruences and Complex Multiplication [PDF]

open access: yes, 2012
We study congruences involving truncated hypergeometric series of the form_rF_{r-1}(1/2,...,1/2;1,...,1;\lambda)_{(mp^s-1)/2} = \sum_{k=0}^{(mp^s-1)/2} ((1/2)_k/k!)^r \lambda^k where p is a prime and m, s, r are positive integers.

The difference between the ordinary height and the canonical height on elliptic curves [PDF]

open access: yes, 2008
We estimate the bounds for the difference between the ordinary height and the canonical height on elliptic curves over number fields. Our result is an improvement of the recent result of Cremona, Prickett, and Siksek [J.E. Cremona, M. Prickett, S. Siksek,

On Types of Elliptic Pseudoprimes

open access: yes, 2021
We generalize the notions of elliptic pseudoprimes and elliptic Carmichael numbers introduced by Silverman to analogues of Euler-Jacobi and strong pseudoprimes.
