On integrability of Weingarten surfaces: a forgotten class
Original language description
Rediscovered by a systematic search, a forgotten class of integrable surfaces is shown to disprove the Finkel-Wu conjecture. The associated integrable nonlinear partial differential equation z(yy) + (1/z)(xx) + 2 = 0 possesses a zero curvature representation, a third-order symmetry and a nonlocal transformation to the sine-Gordon equation phi(xi eta) = sin phi. We leave open the problem of finding a Backlund autotransformation and a recursion operator that would produce a local hierarchy.
