Classical W-algebras within the theory of Poisson vertex algebras

  title={Classical W-algebras within the theory of Poisson vertex algebras},
  author={Alberto De Sole and Victor G. Kac and Daniele Valeri},
We review the Poisson vertex algebra theory approach to classical W-algebras. First, we provide a description of the Drinfeld-Sokolov Hamiltonian reduction for the construction of classical W-algebras within the framework of Poisson vertex algebras and we establish, under certain sufficient conditions, the applicability of the Lenard-Magri scheme of integrability and the existence of the corresponding integrable hierarchy of bi-Hamiltonian equations. Then we provide a Poisson vertex algebra… 

Integrable Hamiltonian Hierarchies for Classical Lie Algebras

We prove that any classical affineW -algebraW(g, f ), where g is a classical Lie algebra and f is an arbitrary nilpotent element of g, carries an integrableHamiltonian hierarchy of Lax type

Ja n 20 20 W-algebras via Lax type operators

W -algebras are certain algebraic structures associated to a finite dimensional Lie algebra g and a nilpotent element f via Hamiltonian reduction. In this note we give a review of a recent approach

Dirac reductions and Classical W-algebras

. In the first part of this paper, we generalize Dirac reduction to the extent of non-local Poisson vertex superalgebra and non-local SUSY Poisson vertex algebra cases. Next, we modify this reduction

Local and Non-local Multiplicative Poisson Vertex Algebras and Differential-Difference Equations

We develop the notions of multiplicative Lie conformal and Poisson vertex algebras, local and non-local, and their connections to the theory of integrable differential-difference Hamiltonian

A geometric construction of integrable Hamiltonian hierarchies associated with the classical affine W-algebras

A class of classical affine W-algebras are shown to be isomorphic as differential algebras to the coordinate rings of double coset spaces of certain prounipotent proalgebraic groups. As an


The purpose of this article is to investigate relations between W-superalgebras and integrable super-Hamiltonian systems. To this end, we introduce the generalized Drinfel’dSokolov (D-S) reduction

Classical $${\mathcal{W}}$$W -Algebras and Generalized Drinfeld-Sokolov Bi-Hamiltonian Systems Within the Theory of Poisson Vertex Algebras

We describe of the generalized Drinfeld-Sokolov Hamiltonian reduction for the construction of classical $${\mathcal{W}}$$W -algebras within the framework of Poisson vertex algebras. In this context,

Lectures on Classical W-Algebras

These are lecture notes of lectures given in 1993 in Cortona, Italy. W-algebras appeared in the conformal field theory as extensions of the Virasoro algebra. They are closely connected with

Poisson vertex algebras in the theory of Hamiltonian equations

Abstract.We lay down the foundations of the theory of Poisson vertex algebras aimed at its applications to integrability of Hamiltonian partial differential equations. Such an equation is called

W-Algebras from Soliton Equations and Heisenberg Subalgebras

Abstract We derive sufficient conditions under which the "second" Hamiltonian structure of a class of generalized KdV-hierarchies defines one of the classical W -algebras obtained through

The variational Poisson cohomology

It is well known that the validity of the so called Lenard–Magri scheme of integrability of a bi-Hamiltonian PDE can be established if one has some precise information on the corresponding 1st

Generalized Drinfeld-Sokolov Hierarchies II: The Hamiltonian Structures

In this paper we examine the bi-Hamiltonian structure of the generalized KdV-hierarchies. We verify that both Hamiltonian structures take the form of Kirillov brackets on the Kac-Moody algebra, and

Non-local matrix generalizations ofW-algebras

There is a standard way to define two symplectic (hamiltonian) structures, the first and second Gelfand-Dikii brackets, on the space of ordinarymth-order linear differential


We reconsider the relation between classicalW-algebras and deformations of differential operators, emphasizing the consistency with diffeomorphisms. Generators of theW-algebra that arek-differentials
