These time-dependent coefficients (model parameters or arbitrary elements) are specified via the direct integration of the classifying relations.enWorld Scientific PublishingFisher equationclassifying relationssymmetry classificationexact solutionsDirect approach to a group classification problem: Fisher equation with time-dependent coefficientsArticle
