Abstract:
      This work aims to study the negative-order KdV equation in (3+1)-dimensions which is developed via using the recursion operator of the KdV equation by employing the extended homoclinic test methods. Consequently, a variety of novel multiwave solutions with several free parameters to the considered equation are presented. Moreover, selecting the particular values of parameters, some graphs are plotted to show the spatial structures and dynamics of the resulting solutions. These results enrich the variety of the dynamics in the eld of nonlinear wave.
