Özet
In this work we investigate the integrable cases of the elliptic-hyperbolic-hyperbolic generalized Davey-Stewartson system introduced in Babaoǧlu and Erbay (2004) [6] following the method of Zakharov and Shulman (1980) [3]. This method provides us with a set of algebraic conditions on the parameters of the system, which are just necessary conditions for the system to be integrable by means of the inverse scattering transform. Taking into account the constraints arising from the physical derivation of the generalized Davey-Stewartson system as described in Babaoǧlu and Erbay (2004) [6], we show that this system is integrable only when it can be transformed to an integrable case of the Davey-Stewartson system. © 2013 Elsevier B.V.
