アブストラクト: We study integrability aspects of superstrings on AdS5 x S5. We show that a one parameter family of flat currents, which is equivalent to that obtained by Bena, Polchinski and Roiban, is manifestly invariant under a generalized Z4 transformation. This symmetry is expected to simplify analysis of the currents because the Z4 transformation is an automorphism of PSU(2,2|4), the isometry in the theory. We perform the canonical analysis of the theory. Especially we calculate the Poisson bracket of the currents. This bracket results in an algebra which includes a Schwinger term. Because of the Schwinger term, more work is needed in understanding the quantum integrability properties of the system.
