On the generalized semi-relativistic Schr\"odinger-Poisson system in R^n

The Cauchy problem for the semi-relativistic Schr"odinger-Poisson system of equations is studied in ${\mathbb{R}}^n$, $n\ge 1$, for a wide class of nonlocal interactions. Furthermore, the asymptotic behavior of the solution as the mass tends to infinity is rigorously discussed, which corresponds to a non-relativistic limit.
