Abstract
For the first time, the new (3+1)-dimensional Painleve integrable extensions to the Mikhailov-Novikov-Wang equation (MNWE) are constructed. The new extended model is obtained by adding a set of linear terms to the standard (1+1)-dimensional MNWE. These additional terms do not kill the integrability of the new models. However, for checking the integrability of the new models, the Painleve analysis is employed for this purpose. Using the simplified Hirota's scheme, a variety of multiple soliton solutions is obtained by imposing appropriate parameter selections. The extended models to the MNWE provide new insights of the integrable equations.
