Exponentially Localized Solitons in 2 + 1 Dimensionssly, the only known localized objects in 2+1 dimensions were the so-called lump-solutions, which decay algebraically at infinity and have no scattering properties. The use of the Bäcklund transformations (BT) and the non linear superposition formulae led BLMP to discover the existence of e

On the Boundary Conditions of the Davey-Stewartson Equationspecific route we take here is to embed the DS system within the Kadomtsev-Petviashili (KP) evolution equation while maintaining well posedness in time. Even though the equations are particular for our application, we stress that the point of view is general and is applicable in wide generality. In
