Resumen: We will prove a reverse Rogers–Shephard inequality for log-concave functions. In some particular cases, the method used for general log-concave functions can be slightly improved, allowing us to prove volume estimates for polars of \ell _p-diferences of convex bodies under the condition that their polar bodies have opposite barycenters.
