Abstract
In this work, we study the behavior of blow-up solutions to the multidimensional restricted Euler–Poisson equations which are the localized version of the full Euler–Poisson system. We provide necessary conditions for the existence of finite-time blow-up solutions in terms of the initial data, and describe the asymptotic behavior of the solutions near blow-up times. We also identify a rich set of the initial data which yields global bounded solutions.
