报告摘要:In this talk, we will develop an analytical approach to construct the global bounded weak solutions to the initial-boundary value problem of a 3D chemotaxis-Stokes system with porous medium cell diffusion $\Del n^m$ for  $m\ge \f{65}{63}$ and general sensitivity. In particular, this extended the precedent results which asserted global solvability within the larger range $m>\f76$ for general sensitivity  (M Winkler, Calc. Var., 2015)  or  $m>\f98$ for scalar sensitivity  (M Winkler, J. Differential Equations, 2018).  Our proof is based on a new observation on the quasi-energy type functional and on an induction argument.
