摘要

By means of the Hirota bilinear method and symbolic computation,high-order lump-type solutions and a kind of interaction solutions are presented for a (3+ 1)-dimensional nonlinear evolution equation.The high-order lumptype solutions of the associated Hirota bilinear equation are presented,which is a kind of positive quartic-quadraticfunction solution.At the same time,the interaction solutions can also be obtained,which are linear combination solutions of quartic-quadratic-functions and hyperbolic cosine functions.Physical properties and dynamical structures of two classes of the presented solutions are demonstrated in detail by their graphs.
