Abstract

The role of invariants in obtaining exact solutions of di erential equations is reviewed. The examples considered are nonlinear evolution type equations like the Fisher and Fitzhugh-Nagumo equations. Finally, we look directly at an equation (formulated) governing some non-Newtonian uid in a rotating system.
