講座內(nèi)容:
In this talk, we will discuss a fully parabolic Keller-Segel system in a bounded domain with smooth boundary. In contrast to most literature addressing the no-flux/no-flux boundary value problem for chemotaxis systems, we require inhomogeneous Dirichlet signal boundary condition here. A critical exponent distinguishing the global solvability and finite-time singularity is obtained.
