چکیده
In this paper it is shown that, given n ∈ Z ≥3 and a, b, c ∈ Q × , there exists a polynomial d(t) ∈ Q[t] such that the curves over Q(t) given by y 2 = x n + ad(t) resp. y 2 = x n + bd(t) and y 2 = x n + cd(t) all have a Jacobian with positive Mordell-Weil rank over Q(t). Extensions of this result to sets of four curves are discussed, as well as the problem of demanding in addition that d(t) is a square.

On Jacobi Inversion Formulae for Telescopic Curves
For a hyperelliptic curve of genus g, it is well known that the symmetric products of g points on the curve are expressed in terms of their Abel–Jacobi image by the hyperelliptic sigma function (Jacobi inversion formulae). Matsutani and Previato gave a natural generalization of the formulae to the more general algebraic curves defined by y = f(x), which are special cases of (n, s) curves, and d...
متن کاملConcentration of Points and Isomorphism Classes of Hyperelliptic Curves over a Finite Field in Some Thin Families
For a prime p and a polynomial f ∈ Fp[X], we obtain upper bounds on the number of solutions of the congruences f(x) ≡ y (mod p) and f(x) ≡ y (mod p), where (x, y) belongs to an arbitrary square with side length M . Further, we obtain non-trivial upper bounds for the number of hyperelliptic curves Y 2 = X + a2g−1X 2g−1 + . . .+ a1X + a0 over Fp, with coefficients in a 2g-dimensional cube (a0, . ...
متن کاملPencils of quadrics and the arithmetic of hyperelliptic curves
In this article, for any fixed genus g ≥ 1, we prove that a positive proportion of hyperelliptic curves over Q of genus g have points over R and over Qp for all p, but have no points globally over any extension of Q of odd degree. By a hyperelliptic curve over Q, we mean a smooth, geometrically irreducible, complete curve C over Q equipped with a fixed map of degree 2 to P defined over Q. Thus ...
متن کاملIntegral Points on Hyperelliptic Curves
Let C : Y 2 = anX + · · · + a0 be a hyperelliptic curve with the ai rational integers, n ≥ 5, and the polynomial on the right irreducible. Let J be its Jacobian. We give a completely explicit upper bound for the integral points on the model C, provided we know at least one rational point on C and a Mordell–Weil basis for J(Q). We also explain a powerful refinement of the Mordell–Weil sieve whic...
متن کاملHyperelliptic Curves in Characteristic 2
In this paper we prove that there are no hyperelliptic supersingular curves of genus 2n − 1 in characteristic 2 for any integer n ≥ 2. Let F be an algebraically closed field of characteristic 2, and let g be a positive integer. Write h = blog2(g + 1) + 1c, where b c denotes the greatest integer less than or equal to a given real number. Let X be a hyperelliptic curve over F of genus g ≥ 3 of 2-...
