A kinetic theory for strongly coupled dusty plasmas is developed from the Bogolyubov-Born-Green-Kirkwood-Yvon (BBGKY) hierarchy. In these plasmas, interparticle distances are typically much smaller than the Debye length, and the coupling parameter Γd≡qd2IddTd is much larger than unity. (Here qd is the dust charge. Td is the temperature, and dd≡[3/(4πnd)]1/3 is the inter-dust-particle distance.) For such quasi-steady-state plasmas, a theoretical argument is given for the validity of the Vlasov equation in the regimes Γd«1 Γc»Γd»1, where Γc designates the coupling parameter when Coulomb crystallization occurs.
