  • Weakly nonlocal Poisson brackets: Tools, examples, computations
    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.

    • File Set
  • Additional file 1 of An age and space structured SIR model describing the Covid-19 pandemic
    Integration of (9)–(10) with κ = 0 $\kappa=0$ , κ as in (20) and 10 times κ as in (20). Integration of (9) with initial datum as in (10) and the parameters described above. The three integrations differ in the choice of κ, which is assigned the value 0, the values in (20) and 10 times this latter value. The file names are: kappa0.avi corresponding to κ = 0; kappa1.avi corresponding to κ as in (20) kappa2.avi corresponding to 10 times the value of κ in (20). kappa3.avi corresponding to 20 times the value of κ in (20).
