Neglecting the influence of the fluid, and completing the chemotaxis-only subsystem with physical Robin-type boundary conditions for oxygen, we first show that the gradients of its radial solutions in a region between two concentric spheres possessing boundary layer effects as the oxygen diffusion rate ε goes to zero. Then we proceed to show that the full chemotaxis-Navier-Stokes system in the half plane of R^2 also possesses boundary layer effects and the thickness of the boundary layer is of order O(ε^(1/2)). 主办单位：数学与统计学院
