Weakly nonlocal Poisson brackets: tools, examples, computations
arXiv:2101.06467 · doi:10.1016/j.cpc.2022.108284
Abstract
We implement an algorithm for the computation of Schouten bracket of weakly nonlocal Hamiltonian operators in three different computer algebra systems: Maple, Reduce and Mathematica. This class of Hamiltonian operators encompass almost all the examples coming from the theory of (1+1)-integrable evolutionary PDEs
