On the Hamiltonian and Lagrangian structures of time-dependent reductions of evolutionary PDEs
Monica Ugaglia
In this paper we study the reductions of evolutionary PDEs on the manifold of the stationary points of time--dependent symmetries. In particular we describe how that the finite dim…

On a Poisson structure on the space of Stokes matrices
Monica Ugaglia
In this paper we study the map associating to a linear differential operator with rational coefficients its monodromy data. The operator has one regular and one irregular singulari…
