Global Classification of Two-Component Approximately Integrable Evolution Equations
نویسنده
چکیده
We globally classify two-component evolution equations, with homogeneous diagonal linear part, admitting infinitely many approximate symmetries. Important ingredients are the symbolic calculus of Gel’fand and Dikĭı, the Skolem–Mahler–Lech theorem, results on diophantine equations in roots of unity by F. Beukers, and an algorithm of C.J. Smyth.

A Lax Operator Hierarchy for the New Fifth Order Integrable System
We consider the Lax representation of the new two-component coupled integrable system recently discovered by the author. Connection of the hierarchy of infinitely many Lax pairs with each other is presented.
متن کاملIntegrable geometric evolution equations for curves
The vortex filament flow and planar filament flow are examples of evolution equations which commute with Euclidean isometries and are also integrable, in that they induce completely integrable PDE for curvature—the focusing nonlinear Schödinger equation and the mKdV equations, respectively. In this note we outline an approach for classifying integrable geometric evolution equations for planar c...
متن کاملIntegrable Evolution Equations on Spaces of Tensor Densities and Their Peakon Solutions
We study a family of equations defined on the space of tensor densities of weight λ on the circle and introduce two integrable PDE. One of the equations turns out to be closely related to the inviscid Burgers equation while the other has not been identified in any form before. We present their Lax pair formulations and describe their bihamiltonian structures. We prove local wellposedness of the...

Abstract We prove that arbitrary (non-polynomial) scalar evolution equations of orderm ≥ 7, that are integrable in the sense of admitting the canonical conserved densities ρ, ρ, and ρ introduced in [A.V.

متن کاملSome Symmetry Classifications of Hyperbolic Vector Evolution Equations
Motivated by recent work on integrable flows of curves and 1+1 dimensional sigma models, several O(N)-invariant classes of hyperbolic equations Utx = f(U,Ut, Ux) for an N -component vector U(t, x) are considered. In each class we find all scalinghomogeneous equations admitting a higher symmetry of least possible scaling weight. Sigma model interpretations of these equations are presented.
