Abstract
The functionally generalized separable solutions of the generalized porous medium equations with power law and exponential diffusivity are studied by using the conditional Lie-Bäcklund symmetry method. The variant forms of the considered equations, which admit the linear conditional Lie-Bäcklund symmetries, are identified. A number of examples are considered and some exact solutions, defined on the polynomial, trigonometric and exponential invariant subspaces determined by the linear conditional Lie-Bäcklund symmetries, are constructed.
