We consider the one-dimensional porous medium equation ut = (u nux)x+ μ x uux. We derive point transformations of a general class that map this equation into itself or into equations of a similar class. In some cases this porous medium equation is connected with well known equations. With the introduction of a new dependent variable this partial differential equation can be equivalently written...
