NEGATIVE FRICTION OF DARBOUX COSMOLOGICAL FLUIDS

Atmospheric free fall with quadratic resistance when considered from the point of view of the strictly isospectral construction of supersymmetric quantum mechanics is a powerful analogy for the class of Darboux cosmological fluids that we introduced in a previous work. Here, using this analogy, it is shown that the possible accelerating cosmological effects are due to the quadratic negative friction properties with which the Darboux fluids are endowed through the mathematical construction.
