ON THE CONSTRUCTION OF PARTIAL DIFFERENCE SCHEMES II: DISCRETE VARIABLES AND SCHWARZIAN LATTICES [PDF]

open access: yesActa Polytechnica, 2016
In the process of constructing invariant difference schemes which approximate partial differential equations we write down a procedure for discretizing a partial differential equation on an arbitrary lattice.

The Exact Solutions for Several Partial Differential-Difference Equations with Constant Coefficients

open access: yesMathematics, 2022
This article is concerned with the description of the entire solutions of several Fermat type partial differential-difference equations (PDDEs) μf(z)+λfz1(z)2+[αf(z+c)−βf(z)]2=1, and μf(z)+λ1fz1(z)+λ2fz2(z)2+[αf(z+c)−βf(z)]2=1, where fz1(z)=∂f∂z1 and fz2(

C-Integrability Test for Discrete Equations via Multiple Scale Expansions [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2010
In this paper we are extending the well known integrability theorems obtained by multiple scale techniques to the case of linearizable difference equations. As an example we apply the theory to the case of a differential-difference dispersive equation of

On the discrete and continuous Miura Chain associated with the Sixth Painlevé Equation [PDF]

open access: yes, 1999
A Miura chain is a (closed) sequence of differential (or difference) equations that are related by Miura or B\"acklund transformations. We describe such a chain for the sixth Painlev\'e equation (\pvi), containing, apart from \pvi itself, a Schwarzian ...

Symmetries of the Hirota Difference Equation [PDF]

open access: yes, 2017
Continuous symmetries of the Hirota difference equation, commuting with shifts of independent variables, are derived by means of the dressing procedure. Action of these symmetries on the dependent variables of the equation is presented.
