The subspaces with dimensions one, two, and three are derived for certain cases of the variable coefficients. The exact solutions of the nonlinear time fractional biological population model are obtained in some cases.eninfo:eu-repo/semantics/closedAccessExact SolutionFractional Biological Population ModelInvariant Subspace MethodRiemann&#8211Liouville Fractional DerivativeArticle10.1002/mma.70632-s2.0-85099014068
