چکیده

Let E be an elliptic curve defined over the rationals and in minimal Weierstrass form, and let P = (x1/z 2 1 , y1/z 3 1) be a rational point of infinite order on E, where x1, y1, z1 are coprime integers. We show that the integer sequence (zn)n>1 defined by nP = (xn/z 2 n, yn/z 3 n) for all n > 1 does not eventually coincide with (un2)n>1 for any choice of linear recurrence sequence (un)n>1 with integer values.

Toeplitz transforms of Fibonacci sequences

We introduce a matricial Toeplitz transform and prove that the Toeplitz transform of a second order recurrence sequence is another second order recurrence sequence. We investigate the injectivity of this transform and show how this distinguishes the Fibonacci sequence among other recurrence sequences. We then obtain new Fibonacci identities as an application of our transform.

Primitive Prime Divisors in Polynomial Arithmetic Dynamics

The question of which terms of a recurrence sequence fail to have primitive prime divisors has been significantly studied for several classes of linear recurrence sequences and for elliptic divisibility sequences. In this paper, we consider the question for sequences generated by the iteration of a polynomial. For two classes of polynomials f(x) ∈ Z[x] and initial values a1 ∈ Z, we show that th...

Elliptic Hypergeometric Solutions to Elliptic Difference Equations⋆

It is shown how to define difference equations on particular lattices {xn}, n ∈ Z, made of values of an elliptic function at a sequence of arguments in arithmetic progression (elliptic lattice). Solutions to special difference equations have remarkable simple interpolatory expansions. Only linear difference equations of first order are considered here.

On The Elliptic Divisibility Sequences over Finite Fields

In this work we study elliptic divisibility sequences over finite fields. Morgan Ward in [11, 12] gave arithmetic theory of elliptic divisibility sequences. We study elliptic divisibility sequences, equivalence of these sequences and singular elliptic divisibility sequences over finite fields Fp, p > 3 is a prime. Keywords—Elliptic divisibility sequences, equivalent sequences, singular sequence...

On the Distribution of the Subset Sum Pseudorandom Number Generator on Elliptic Curves

Given a prime p, an elliptic curve E/Fp over the finite field Fp of p elements and a binary linear recurrence sequence (u(n))∞n=1 of order r, we study the distribution of the sequence of points r−1 ∑ j=0 u(n+ j)Pj , n = 1, . . . , N, on average over all possible choices of Fp-rational points P1, . . . , Pr on E . For a sufficiently large N we improve and generalise a previous result in this dir...
