Odd Hamiltonian Structure for Supersymmetric Sawada - Kotera Equation

Abstract

We study the supersymmetric N=1 hierarchy connected with the Lax operator of the supersymmetric Sawada-Kotera equation. This operator produces the physical equations as well as the exotic equations with odd time. The odd Bi-Hamiltonian structure for the N=1 Supersymmetric Sawada - Kotera equation is defined. The product of the symplectic and implectic Hamiltonian operator gives us the recursion operator. In that way we prove the integrability of the supersymmetric Sawada - Kotera equation in the sense that it has the Bi-Hamiltonian structure. The so called "quadratic" Hamiltonian operator of even order generates the exotic equations while the "cubic" odd Hamiltonian operator generates the physical equations.
