Variational/Symplectic and Hamiltonian Operators Mark E. Fels |

Аннотация: Given a differential equation (or system) $$Q\Delta=E(L),$$ where $$D_x(u_t - u_{xxx}) = u_{tx}-u_{xxxx}=E(-\frac12(u_tu_x+u_{xx}^2)).$$ Here This talk will discuss how the variational operator problem can be solved in the case of scalar evolution equations and how variational operators are related to symplectic and Hamiltonian operators.
