Normal forms of hierarchies of integrable PDEs, Frobenius manifolds and Gromov-Witten invariants

by Boris Dubrovin, Youjin Zhang , 2001
"... We present a project of classification of a certain class of bihamiltonian 1+1 PDEs depending on a small parameter. Our aim is to embed the theory of Gromov- Witten invariants of all genera into the theory of integrable systems. The project is focused at describing normal forms of the PDEs and their ..."

The Riemann-Hilbert Formalism For Certain Linear and Nonlinear Integrable PDEs

by Dimitrios A Pinotsis A , 2007
"... We show that by deforming the Riemann-Hilbert (RH) formalism associated with certain linear PDEs and using the so-called dressing method, it is possible to derive in an algorithmic way nonlinear integrable versions of these equations. In the usual Dressing Method, one first postulates a matrix RH pr ..."

The Geometry of Peaked Solitons and Billiard Solutions of a Class of Integrable PDE’s ∗

by Darryl D. Holm, Jerrold E. Marsden
"... The purpose of this letter is to investigate the geometry of new classes of solitonlike solutions for integrable nonlinear equations. One example is the class of peakons introduced by Camassa and Holm [1993] for a shallow water equation. We put this equation in the framework of complex integrable Ha ..."

A hierarchy of integrable PDEs in 2+1 dimensions associated with 2 - dimensional vector fields

by S. V. Manakov, P. M. Santini , 2006
"... We study a hierarchy of integrable partial differential equations in 2 + 1 dimensions arising from the commutation of 2- dimensional vector fields, and we construct the formal solution of the associated Cauchy problems using the Inverse Scattering Transform for one-parameter families of vector field ..."

Implicit-Explicit Methods For Time-Dependent PDEs

by Uri M. Ascher, Steven J. Ruuth, Brian T. R. Wetton - SIAM J. NUMER. ANAL , 1997
"... Implicit-explicit (IMEX) schemes have been widely used, especially in conjunction with spectral methods, for the time integration of spatially discretized PDEs of diffusion-convection type. Typically, an implicit scheme is used for the diffusion term and an explicit scheme is used for the convection ..."

Multisymplectic geometry, variational integrators, and nonlinear PDEs

by Jerrold E. Marsden, George W. Patrick, Steve Shkoller - Comm. Math. Phys , 1998
"... Abstract: This paper presents a geometric-variational approach to continuous and discrete mechanics and field theories. Using multisymplectic geometry, we show that the existence of the fundamental geometric structures as well as their preservation along solutions can be obtained directly from the v ..."

have these important preservation properties, then follow by choosing a discrete action functional. In the case of mechanics, we recover the variational symplectic integrators of Veselov type, while for PDEs we obtain covariant spacetime integrators which conserve the corresponding discrete
