Lump and Interaction Solutions of Linear PDEs in (3 + 1)-Dimensions

Linear partial differential equations in (3 + 1)-dimensions consisting of all mixed second-order derivatives are considered, and Maple symbolic computations are made to construct their lump and interaction solutions, including lump-periodic, lumpkink and lump-soliton solutions.
