Consider an elliptic curve C with coefficients in K with [ K : Q ] < ∞ and δ ∈ C ( K ) a non torsion point. We consider an elliptic difference equation P li =0 a i ( p ) f ( p ⊕ i.δ ) = 0 with ⊕ the elliptic addition law and a i polynomials on C . We present an algorithm to compute rational solutions, then an intermediary class we call pseudo-rational solutions, and finally hyperexponential solutions, which are functions f such that f ( p ⊕ δ ) /f ( p ) is rational over C .

The Arithmetic of Elliptic Curves

TLDR
This research focuses on 9 specific elliptic curves E over Q, each with complex multiplication by the maximal order in an imaginary quadratic field, defined by the generators ω1, ω2 ∈ C of the period lattice.

Galois Groups of Difference Equations of Order Two on Elliptic Curves

This paper is concerned with difference equations on elliptic curves. We establish some general properties of the difference Galois groups of equations of order two, and give applications to the

Hypergeometric Solutions of First-Order Linear Difference Systems with Rational-Function Coefficients

Differential transcendence criteria for second-order linear difference equations and elliptic hypergeometric functions

We develop general criteria that ensure that any non-zero solution of a given second-order difference equation is differentially transcendental, which apply uniformly in particular cases of interest,
