Inelastic Boltzmann Equation Driven by a Particle Thermal Bath

We consider the spatially inhomogeneous Boltzmann equation for inelastic hard-spheres, with constant restitution coefficient $\alpha \in (0,1)$, under the thermalization induced by a host medium with a fixed Maxwellian distribution and any fixed $e\in (0,1]$. When the restitution coefficient $\alpha$ is close to 1 we prove existence and uniqueness of global solutions considering the close-to-equilibrium regime. We also study the long-time behaviour of these solutions and prove a convergence to equilibrium with an exponential rate.
