On the classification of group invariant solutions of the Barenblatt–Gilman model by a one-dimensional system of subalgebras

The Barenblatt–Gilman (BG) equation, which simulates nonequilibrium countercurrent capillary impregnation, is discussed in this study. By applying symmetry classification to the nonlinear function Φ(σ), six distinct cases emerge. In the general case, Φ(σ) yields a three-dimensional principal algebra...
