On a class of integrable Hamiltonian equations in 2+1 dimensions
B. Gormley, E. V. Ferapontov, V. S. Novikov
We classify integrable Hamiltonian equations in 3D with the Hamiltonian operator d/dx, where the Hamiltonian density h(u, w) is a function of two variables: dependent variable u an…

Dispersionless Hirota equations and the genus 3 hyperelliptic divisor
Fabien Cléry, Evgeny V. Ferapontov
Equations of dispersionless Hirota type have been thoroughly investigated in the mathematical physics and differential geometry literature. It is known that the parameter space of…
