WDVV equations and invariant bi-Hamiltonian formalism
WDVV equations and invariant bi-Hamiltonian formalism
A bstract The purpose of the paper is to show that, in low dimensions, the WDVV equations are bi-Hamiltonian. The invariance of the bi-Hamiltonian formalism is proved for N = 3. More examples in higher dimensions show that the result might hold in general. The invariance group of the bi-Hamiltonian …
