Nonlinear self-adjointness is shown and conservation laws are calculated too. Some scientific theorems have been given in this paper.eninfo:eu-repo/semantics/closedAccessPopulation ModelNonclassical SymmetryNonlinear Self-AdjointnessHeir EquationsNonlinear Self-Adjointness and Nonclassical Solutions of a Population Model with Variable CoefficientsArticle71103109N/AWOS:00043799310001510.1166/jap.2018.1387
