Abstract
We aim at seeking nonlinearity-managed lump waves in a spatial symmetric HSI model. Nonlinear terms play an important role in formulating such lump waves with the dispersion terms in the nonlinear model. Based on an associated Hirota bilinear form, an ansatz on quadratic function solutions is adopted for the corresponding Hirota bilinear equation, and symbolic computation with Maple is made to construct the required lump waves. A few of characteristic properties of the obtained lump waves are determined and some concluding remarks are given.
