内容摘要:In this talk we consider the initial-boundary value problem for a Keller-Segel-Navier-Stokes system in a bounded domain Ω ⊂ R ^N (N = 2,3) with smooth boundary. For the 2D case, we shall prove that any arbitrarily small algebraic saturation effect in the chemotactic sensitivity at large densities is sufficient to rule out any blow-up phenomenon. In the 3D case setting, we shall establish the existence of global weak solutions under some suitable saturation assumption of the sensitivity.
