An Algorithm Determining the Difference Galois Group of Second Order Linear Difference Equations
نویسنده
چکیده
groups are the groups Dk,l,e = {( α 0 0 δ ) ∈ D | α = 1, δ = 1, ααδδ = 1 } with l, k, e ∈ Z≥1 and gcd(k, l, e) = 1, where gα = k gcd(k,l) and gδ = l gcd(k,l) . If G is a one-dimensional algebraic subgroup of D then G is equal to a group Dm,n = {( α 0 0 δ ) ∈ D | αδ = 1 } with m,n ∈ Z. For all m,n ∈ Z we have that Dm,n/D m,n

متن کاملNON-STANDARD FINITE DIFFERENCE METHOD FOR NUMERICAL SOLUTION OF SECOND ORDER LINEAR FREDHOLM INTEGRO-DIFFERENTIAL EQUATIONS
In this article we have considered a non-standard finite difference method for the solution of second order Fredholm integro differential equation type initial value problems. The non-standard finite difference method and the composite trapezoidal quadrature method is used to transform the Fredholm integro-differential equation into a system of equations. We have also developed a numerical met...
متن کاملComputing the differential Galois group of a one-parameter family of second order linear differential equations
We develop algorithms to compute the differential Galois group corresponding to a one-parameter family of second order homogeneous ordinary linear differential equations with rational function coefficients. More precisely, we consider equations of the form ∂2Y ∂x2 + r1 ∂Y ∂x + r2Y = 0, where r1,r2 ∈C(x, t) and C is an algebraically closed field of characteristic zero. We work in the setting of ...
متن کاملAlgebraic and Algorithmic Aspects of Difference Equations∗
In this course, I will give an elementary introduction to the Galois theory of linear difference equations. This theory shows how to associate a group of matrices with a linear difference equation and shows how group theory can be used to determine properties of the solutions of the equations. I will begin by giving an introduction to the theory of linear algebraic groups, those groups that occ...
متن کاملGalois 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 calculation of some difference Galois groups. For instance, our results combined with a result from transcendence theory due to Schneider allow us to identify a large class of discrete Lamé equations wi...
