A pseudodifferential operator L(∂) of order N is called a Lax operator if the Lax equations ∂L ∂tk = [(L k N )+, L] are non-zero and consistent for infinitely many positive integers k. In the present paper we discuss properties of Lax operators along the lines of the theory of KP and n-KdV hierarchies.

A New Scheme of Integrability for (bi)Hamiltonian PDE
We develop a new method for constructing integrable Hamiltonian hierarchies of Lax type equations, which combines the fractional powers technique of Gelfand and Dickey, and the classical HamiltonianExpand

New types of reductions of the Kadomtsev–Petviashvili (KP) hierarchy are considered on the basis of Sato’s approach. Within this approach the KP hierarchy is represented by infinite sets of equationsExpand
Tau function of the CKP hierarchy and nonlinearizable virasoro symmetries
We introduce a single tau function that represents the C-type Kadomtsev–Petviashvili (CKP) hierarchy in a generalized Hirota 'bilinear' equation. The actions on the tau function by additionalExpand

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 calledExpand
