Phantom k-essence cosmologies
We devise a method to obtain a phantom version of FRW k-essence cosmologies with homogeneous k fields by applying form-invariance transformations. It can be seen that the transformation performs the maps [Formula Presented] and [Formula Presented] which in turn give [Formula Presented] and [Formula...
