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, 2019
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 ...

Constructing Cycles in Isogeny Graphs of Supersingular Elliptic Curves

open access: yesJournal of Mathematical Cryptology, 2021
Loops and cycles play an important role in computing endomorphism rings of supersingular elliptic curves and related cryptosystems. For a supersingular elliptic curve E defined over 𝔽p2, if an imaginary quadratic order O can be embedded in End(E) and a ...

A classification of isogeny‐torsion graphs of Q‐isogeny classes of elliptic curves

open access: yesTransactions of the London Mathematical Society, 2021
Let E be a Q‐isogeny class of elliptic curves defined over Q. The isogeny graph associated to E is a graph which has a vertex for each elliptic curve in the Q‐isogeny class E, and an edge for each cyclic Q‐isogeny of prime degree between elliptic curves ...

Rank zero elliptic curves induced by rational Diophantine triples [PDF]

open access: yes, 2020
Rational Diophantine triples, i.e. rationals a,b,c with the property that ab+1, ac+1, bc+1 are perfect squares, are often used in construction of elliptic curves with high rank. In this paper, we consider the opposite problem and ask how small can be the

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.

Orienting supersingular isogeny graphs

open access: yesJournal of Mathematical Cryptology, 2020
We introduce a category of 𝓞-oriented supersingular elliptic curves and derive properties of the associated oriented and nonoriented ℓ-isogeny supersingular isogeny graphs.

Models of hyperelliptic curves with tame potentially semistable reduction

open access: yesTransactions of the London Mathematical Society, Volume 7, Issue 1, Page 49-95, December 2020., 2020
Abstract Let C be a hyperelliptic curve y2=f(x) over a discretely valued field K. The p‐adic distances between the roots of f(x) can be described by a completely combinatorial object known as the cluster picture. We show that the cluster picture of C, along with the leading coefficient of f and the action of Gal(K¯/K) on the roots of f, completely ...

Different approach on elliptic curves mathematical models study and their applications

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2022
In a research project in which a group of mathematical researchers is involved, it was necessary to create a system of nonlinear equations defined over a particular nonsupersingular elliptic space.

Conductor and discriminant of Picard curves

open access: yesJournal of the London Mathematical Society, Volume 102, Issue 1, Page 368-404, August 2020., 2020
Abstract We describe normal forms and minimal models of Picard curves, discussing various arithmetic aspects of these. We determine all so‐called special Picard curves over Q with good reduction outside 2 and 3, and use this to determine the smallest possible conductor a special Picard curve may have.

Torsion subgroups of rational Mordell curves over some families of number fields

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2022
Mordell curves over a number field K are elliptic curves of the form y2 = x3 + c, where c ∈ K \ {0}. Let p ≥ 5 be a prime number, K a number field such that [K : ℚ] ∈ {2p, 3p}.
