Title: Bi-Hamiltonian systems from homogeneous operators, part 2
Abstract:
I will present new results on the same topic on which I delivered a seminar on March 2026. More precisely, the topic is that of integrable systems defined by bi-Hamiltonian pairs of the following form: and , where , are homogeneous first-order Hamiltonian operators and is a homogeneous Hamiltonian operator of degree (order) . Many 'famous' integrable systems (KdV, AKNS, dispersive water waves etc.) are endowed with a bi-Hamiltonian pair of that form. We will illustrate recent advances on compatibility conditions and their geometric interpretation. The results will be published in arXiv soon.
