Interacting fluids generating identical, dual and phantom cosmologies

We find the group of symmetry transformations generated by interacting fluids in spatially flat Friedmann-Robertson-Walker (FRW) spacetime which links cosmologies with the same scale factor (identity) or with scale factors a and a-1 (duality). There exists a duality between contracting and superacce...
