We introduce a notion of visibility for Mordell-Weil groups, make a conjecture about visibility, and support it with theoretical evidence and data. These results shed new light on relations between Mordell-Weil and Shafarevich-Tate groups. 11G05, 11G10, 11G18, 11Y40

We study the growth and stability of Mordell–Weil group Tate–Shafarevich an elliptic curve defined over rationals, in various cyclic Galois extensions prime power order. Mazur Rubin introduced notion diophantine for $$E_{/{{\mathbb {Q}}}}$$ at a given p. Inspired by their definition group, we introduce analogous called -stability. From perspective Iwasawa theory, it benefits us to stronger grou...

In this paper, a super-optimal pairing based on the Weil pairing is proposed with great efficiency. It is the first approach to reduce the Miller iteration loop when computing the variants of the Weil pairing. The super-optimal pairing based on the Weil pairing is computed rather fast, while it is slightly slower than the previous fastest pairing on the corresponding elliptic curves.

Let E be an optimal elliptic curve over Q of conductor N having analytic rank one, i.e., such that the L-function LE(s) of E vanishes to order one at s = 1. Let K be a quadratic imaginary field in which all the primes dividing N split and such that the L-function of E over K vanishes to order one at s = 1. Suppose there is another optimal elliptic curve over Q of the same conductor N whose Mord...

Let E be an optimal elliptic curve over Q of conductor N having analytic rank zero, i.e., such that the L-function LE(s) of E does not vanish at s = 1. Suppose there is another optimal elliptic curve over Q of the same conductor N whose Mordell-Weil rank is greater than zero and whose associated newform is congruent to the newform associated to E modulo a power r of a prime p. The theory of vis...

Let A be a quotient of J0(N) associated to a newform f such that the special L-value of A (at s = 1) is non-zero. We give a formula for the ratio of the special L-value to the real period of A that expresses this ratio as a rational number. We extract an integer factor from the numerator of this formula; this factor is non-trivial in general and is related to certain congruences of f with eigen...

The Birch and Swinnerton-Dyer conjecture states that the rank of the Mordell-Weil group of an elliptic curve E equals the order of vanishing at the central point of the associated L-function L(s, E). Previous investigations have focused on bounding how far we must go above the central point to be assured of finding a zero, bounding the rank of a fixed curve or on bounding the average rank in a ...
