Ea. Saied et Mm. Hussein, NEW CLASSES OF SIMILARITY SOLUTIONS OF THE INHOMOGENEOUS NONLINEAR DIFFUSION-EQUATIONS, Journal of physics. A, mathematical and general, 27(14), 1994, pp. 4867-4874
The Lie similarity method has been used to extend the similarity solut
ions of the one-dimensional inhomogeneous nonlinear diffusion equation
s. We determine the Lie point symmetry vector fields and calculate the
similarity ansatz. Then we discuss the resulting nonlinear ordinary d
ifferential equations. Exact solutions are found, and their relations
to some real physical are discussed.
