Spectral gap and irreducibility for collisional transport semigroups with general vector fields

Motivated by kinetic theory, this paper investigates the spectral theory and long-time asymptotics of semigroups $ \left( W(t)\right) _{t\geq 0} $ associated with integro-differential equations $ \frac{\partial f}{\partial t} +a.\frac{\partial f}{\partial x}+b.\frac{\partial f}{\...
