Item 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.Item Lie Group Analysis of a Forced KdV Equation(Hindawi Publishing Corporation, 2013) Molati, M.; Khalique, C. M.Item Symmetry classification and invariant solutions of the variable coefficient BBM equation(Elsevier, 2013) Molati, M.; Khalique, C. M.We perform Lie symmetry classification of a time-variable coefficient BBM equation, which arises in the modeling of long waves of small amplitude in �1 � 1� dimensions. The direct method of group classification is employed to specify the forms of these time-dependent coefficients. Some exact solutions are derived.
