Summary: Initial value problems and solutions associated with the Kadomtsev-Petviashvili equation \[ (u_t+u_{xxx}+6uu_x)_x+3 \varepsilon^2u_{yy}=0, \] are analyzed. The discussion includes the inverse scattering transform for suitably decaying data, solutions decaying off a background line multi-pole lump soliton solutions and solutions which are slowly decaying. Existence and uniqueness of the associated eigenfunctions are discussed in terms of natural functional norms.
