Covariant symplectic structure of the complex Monge-Ampère equation
Y. Nutku
The complex Monge-Ampère equation admits covariant bi-symplectic structure for complex dimension 3, or higher. The first symplectic 2-form is obtained from a new variational formul…

Alternative bi-Hamiltonian structures for WDVV equations of associativity
J. Kalayci, Y. Nutku
The WDVV equations of associativity in 2-d topological field theory are completely integrable third order Monge-Ampère equations which admit bi-Hamiltonian structure. The time vari…
