Xb. Hu et R. Willox, SOME NEW EXACT-SOLUTIONS OF THE NOVIKOV-VESELOV EQUATION, Journal of physics. A, mathematical and general, 29(15), 1996, pp. 4589-4592
The Novikov-Veselov (NV) equation is considered. Using Backlund transf
ormations and a nonlinear superposition formula for the NV equation, s
ome new exact solutions to this equation are found, among which are th
e so-called one- and two-lump solutions.
