Seminar GDEq. Local Lagrangian densities and 3D integrable systems

30.09.26 Speaker: Maxim Pavlov Title: Local Lagrangian densities and 3D integrable systems Abstract: We discuss the existence of local Lagrangian densities for integrable systems in three dimensions. Our Observation: A few members of the Darboux-KP hierarchy possess local Lagrangian densities only. These examples will be presented and discussed.
