摘 要: | The chemotaxis-Navier-Stokes system ■is considered in a smoothly bounded planar domain Ω under the boundary conditions■ with a given nonnegative constant c_*.It is shown that if(n0,c0,u0) is sufficiently regular and such that the product ■is suitably small,an associated initial value problem possesses a bounded classical solution with(n,c,u)|t=0=(n0,c0,u0).
