摘要：

We study the large time behavior of Fujita-Kato type solutions to the Vlasov-Navier-Stokes system set on T3xR3. Under the assumption that the initial so-called modulated energy is small enough, we prove that the distribution function converges to a Dirac mass in velocity, with exponential rate. The proof is based on the fine structure of the system and on a bootstrap analysis allowing us to get global bounds on moments.
