چکیده
In this paper we construct the autonomous quad-equations which admit as symmetries five-point differential-difference equations belonging to known lists found by Garifullin, Yamilov and Levi. The obtained are classified up point transformations some simple non-autonomous transformations. We discuss our results in framework of literature. There among them a few new examples both sine-Gordon Liouville type equations.

Discrete derivatives and symmetries of difference equations
We show on the example of the discrete heat equation that for any given discrete derivative we can construct a nontrivial Leibniz rule suitable to find the symmetries of discrete equations. In this way we obtain a symmetry Lie algebra, defined in terms of shift operators, isomorphic to that of the continuous heat equation.
متن کاملAsymmetric Integrable Quad-graph Equations
Integrable difference equations commonly have more low-order conservation laws than occur for non-integrable difference equations of similar complexity. We use this empirical observation to sift a large class of difference equations, in order to find candidates for integrability. It turns out that all such candidates have an equivalent affine form. These are tested by calculating their algebrai...
متن کاملCauchy problem for integrable discrete equations on quad-graphs
Initial value problems for the integrable discrete equations on quadgraphs are investigated. We give a geometric criterion of when such a problem is well-posed. In the basic example of the discrete KdV equation an effective integration scheme based on the matrix factorization problem is proposed and the interaction of the solutions with the localized defects in the regular square lattice are di...
متن کاملClassification of Second-order Ordinary Differential Equations Admitting Lie Groups of Fibre-preserving Point Symmetries
We use Elie Cartan's method of equivalence to give a complete classification, in terms of differential invariants, of second-order ordinary differential equations admitting Lie groups of fibre-preserving point symmetries. We then apply our results to the determination of all second-order equations which are equivalent, under fibre-preserving transformations, to the free particle equation. In ad...
متن کاملFirst Integrals/Invariants & Symmetries for Autonomous Difference Equations
For the autonomous kth order difference equation xn+k = f(xn, xn+1, . . . , xn+k−1), where f ∈ C[U ] with domain U ⊂ R, a global first integral/invariant for this difference equation is a nonconstant function H ∈ C[U ], with H : U → R, which remains invariant on the forward orbit Γ(x0, x1, . . . , xk−1). If a first integral exists, then it satisfies a particular functional difference equation a...
