Constructing phantom cosmologies from standard scalar field universes

We illustrate how form-invariance transformations can be used for constructing phantom cosmologies from standard scalar field universes. First we discuss how to relate two flat Friedmann-Robertson-Walker cosmologies with different barotropic indexes [Formula presented] and [Formula presented]. Then...
