We develop the symbolic representation method to derive the hierarchies of (2+1)-dimensional integrable equations from the scalar Lax operators and to study their properties globally. The method applies to both commutative and noncommutative cases in the sense that the dependent variable takes its values in C or a noncommutative associative algebra. We prove that these hierarchies are indeed quasi-local in the commutative case as conjectured by Mikhailov and Yamilov [J. Phys. A 31, 6707 (1998… 
Representations of sl(2, ℂ) in category O and master symmetries
We show that the indecomposable sl(2,ℂ)-modules in the Bernstein-Gelfand-Gelfand category O naturally arise for homogeneous integrable nonlinear evolution systems. We then develop a new approach
Notes on exact multi-soliton solutions of noncommutative integrable hierarchies
We study exact multi-soliton solutions of integrable hierarchies on noncommutative space-times which are represented in terms of quasi-determinants of Wronski matrices by Etingof, Gelfand and Retakh.
Towards the classification of integrable differential–difference equations in 2 + 1 dimensions
We address the problem of classification of integrable differential–difference equations in 2 + 1 dimensions with one/two discrete variables. Our approach is based on the method of hydrodynamic
Integrable equations in 2 + 1 dimensions: deformations of dispersionless limits
We classify integrable third-order equations in 2 + 1 dimensions which generalize the examples of Kadomtsev–Petviashvili, Veselov–Novikov and Harry Dym equations. Our approach is based on the
Symbolic Representation and Classification of N=1 Supersymmetric Evolutionary Equations
We extend the symbolic representation to the ring of N=1 supersymmetric differential polynomials, and demonstrate that operations on the ring, such as the super derivative, Fréchet derivative, and
Number Theory and the Symmetry Classification of Integrable Systems
The theory of integrable systems has developed in many directions, and although the interconnections between the different subjects are clearly suggested by the similarity of the results, they are
On the classification of scalar evolutionary integrable equations in 2 + 1 dimensions
We consider evolutionary equations of the form ut = F(u, w) where w=Dx−1Dyu is the nonlocality, and the right hand side F is polynomial in the derivatives of u and w. The recent paper [Ferapontov,
Soliton Scattering in Noncommutative Spaces
We discuss exact multisoliton solutions of integrable hierarchies on noncommutative space–times in various dimensions. The solutions are represented by quasideterminants in compact forms. We study
Two-component generalizations of the Camassa–Holm equation
A classification of integrable two-component systems of non-evolutionary partial differential equations that are analogous to the Camassa–Holm equation is carried out via the perturbative symmetry
New integrable ($$3+1$$3+1)-dimensional systems and contact geometry
We introduce a novel systematic construction for integrable ($$3+1$$3+1)-dimensional dispersionless systems using nonisospectral Lax pairs that involve contact vector fields. In particular, we


Commuting flows and conservation laws for noncommutative Lax hierarchies
We discuss commuting flows and conservation laws for Lax hierarchies on noncommutative spaces in the framework of the Sato theory. On commutative spaces, the Sato theory has revealed essential
Towards classification of -dimensional integrable equations. Integrability conditions I
In this paper we attempt to extend the symmetry approach (well developed in the case of (1 + 1)-dimensional equations) to the (2 + 1)-dimensional case. Presence of nonlocal terms in symmetries and
Hamiltonian theory over noncommutative rings and integrability in multidimensions
A generalization of the Adler–Gel’fand–Dikii scheme is used to generate bi‐Hamiltonian structures in two spatial dimensions. In order to implement this scheme, a Hamiltonian theory is built over a

This paper is devoted to the complete classification of integrable one‐component evolution equations whose field variable takes its values in an associative algebra. The proof that the list of

We show the existence of infinitely many symmetries for λ-homogeneous equations when λ=0. If the equation has one generalized symmetry, we prove that it has infinitely many and these can be produced

On Classification of Integrable Nonevolutionary Equations
We study partial differential equations of second order (in time) that possess a hierarchy of infinitely many higher symmetries. The famous Boussinesq equation is a member of this class after the
