Cosymmetries and Nijenhuis recursion operators for difference equations
Alexander V. Mikhailov, Jing Ping Wang, Pavlos Xenitidis
In this paper we discuss the concept of cosymmetries and co--recursion operators for difference equations and present a co--recursion operator for the Viallet equation. We also dis…
The Hunter-Saxton equation: remarkable structures of symmetries and conserved densities
Jing Ping Wang
In this paper, we present extraordinary algebraic and geometrical structures for the Hunter-Saxton equation: infinitely many commuting and non-commuting -independent higher or…
Recursion operators, conservation laws and integrability conditions for difference equations
Alexander V. Mikhailov, Jing Ping Wang, Pavlos Xenitidis
In this paper we make an attempt to give a consistent background and definitions suitable for the theory of integrable difference equations. We adapt a concept of recursion operato…
