On the Riccati dynamics of 2D EulerPoisson equations with attractive forcing

The Euler–Poisson (EP) system describes the dynamic behaviour of many important physical flows. In this work, a Riccati system that governs pressureless two-dimensional EP equations is studied. The evolution of divergence is governed by the Riccati type equation with several nonlinear/nonlocal terms...
