On a class of three-dimensional integrable Lagrangians

E. V. Ferapontov, K. R. Khusnutdinova, S. P. Tsarev

We characterize non-degenerate Lagrangians of the form $\int f (u_{x}, u_{y}, u_{t}) d x d y d t$ such that the corresponding Euler-Lagrange equations $ (f_{u_x})_x+ (f_{u_y})_y+ (f_{u_t})…

Tri-Hamiltonian Structures of The Egorov Systems

M. V. Pavlov, S. P. Tsarev

The description of the Egorov hydrodynamic type systems is presented in language of conservation laws. Under extra conditions of semisimplicity and homogeneity tri-Hamiltonian stru…
