Enhanced group analysis and exact solutions of variable coefficient semilinear diffusion equations with a power source
(2009)A new approach to group classification problems and more general investigations on transformational properties of classes of differential equations is proposed. It is based on mappings between classes of differential ...

Group classification of systems of diffusion equations
(2017)Group classification of a class of systems of diffusion equations is carried out. Arbitrary elements that appear in the system depend on two variables. All forms of the arbitrary elements that provide additional Lie ...
