Query: Scattering theory for a class of radial focusing inhomogeneous Hartree
  equations   This paper studies the asymptotic behavior of global solutions to the
generalized Hartree equation $$i\dot u+\Delta u+(I_\alpha
*|\cdot|^b|u|^p)|x|^b|u|^{p-2}u=0 .$$ Indeed, using a new approach due to
\cite{dm}, one proves the scattering of the above inhomogeneous Choquard
equation in the mass-super-critical and energy sub-critical regimes with radial
setting.
