Item Metadata only Direct approach to a group classification problem: Fisher equation with time-dependent coefficients(World Scientific Publishing, 2016) Molati, M.; Khalique, C. M.We perform Lie symmetry analysis of a time-variable coefficient Fisher equation which models reaction–diffusion–convection phenomena in biological, chemical and physical systems. These time-dependent coefficients (model parameters or arbitrary elements) are specified via the direct integration of the classifying relations.
