The paper deals with the Cauchy problem of coupled chemotaxis-fluid equations. By taking advantage of a coupling structure of the equations and using the semigroup approach, we show existence and asymptotic stability with small initial data and external force (u0,n0,∇c0,c0)∈N˙r1,λ,∞−β1×N˙r2,λ,∞−β2×N...
