Abstract:
In this talk, we consider a doubly degenerate chemotaxis-consumption system in non-convex domain when $N\ge 2$. We prove that for any suitably regular initial data, this system admits global bounded weak solutions. Furthermore, we also study the large time behavior for the solutions we obtained by using the Moser iteration technique and obtaining a new Harnack-type inequality.
