报告摘要一：
In this talk, we will first review some recent results on the Keller-Segel(-fluid) system.Then we consider the convergence of solutions to a class of parabolic-parabolic Keller-Segel-Navier-Stokes systems to the solution of the parabolic-elliptic counterpart. Under appropriate assumptions on the model ingredients, we derive a general result which asserts certain strong and pointwise convergence properties and will be concretized in the context of two examples. This is a joint work with Professor Michael Winkler and Professor Yulan Wang.
报告摘要二：
In this talk, we consider an initial-boundary value problem for a chemotaxis-(Navier-)Stokes system in a bounded convex domain Ω ⊂R2 with smooth boundary. We concerns the limit problem in which the convection term in the Navier-Stokes system disappears and the Navier-Stokes part reduces to a forced evolutionary Stokes. The main result asserts temporally uniform convergence of solutions of the chemotaxis-Navier-Stokes system to the solution of its chemotaxis-Stokes counterpart.
