Title: Nonlocal homogeneous third-order Hamiltonian operators
Abstract:
We start with a short review of results on local homogeneous third-order Hamiltonian operators:
1. Potemin system (skew-symmetry conditions and consequences of Jacobi identity).
2. Monge metric and conditions on its coefficients.
3. Classifications in two- three- and four-component cases.
Then we will discuss nonlocal operators that arise via Dirac reductions.
