Conformal geometry of the (discrete) Schwarzian Davey-Stewartson II hierarchy
arXiv:nlin/0312030
Abstract
The conformal geometry of the Schwarzian Davey-Stewartson II hierarchy and its discrete analogue is investigated. Connections with discrete and continuous isothermic surfaces and generalised Clifford configurations are recorded. An interpretation of the Schwarzian Davey-Stewartson II flows as integrable deformations of conformally immersed surfaces is given.
