This article examined time-fractional biological population model and gained some new solitary wave structures through the modified (G'/G)-expansion method. Among these results, a few solutions are obtained for the initial time. Finally, we concluded that the examined approach in raise, notable in showing numerous solitary wave structures of various nonlinear space -time-fractional models following in biology, physics and engineering as well.eninfo:eu-repo/semantics/closedAccessModified (G '/G)-Expansion MethodTime Fractional Biological Population ModelSolitary Wave StructuresArticle113N/AQ35970WOS:000530902400005
