摘要: In this talk, we will present recent progress on the suppression of blow-up for the three-dimensional Patlak-Keller-Segel-Navier-Stokes system via the Couette flow. As is well known, for the two-dimensional PKS system, solutions blow up in finite time when the initial cell mass exceeds 8π; for the three-dimensional PKS system, blow-up may occur in finite time for any positive initial cell mass. We prove that when the Couette flow are sufficiently strong, the solutions of the coupled system do not blow up in finite time. It is a joint work with Lili Wang and Wendong Wang.
