Global Existence and Asymptotic Behavior of Classical Solutions for a 3D Two-Species Keller-Segel-Stokes System with Competitive Kinetics

Abstract: This paper deals with the two-species Keller-Segel-Stokes system with competitive kinetics                (n 1 ) t + u · ∇n 1 = ∆n 1 − χ 1 ∇ · (n 1 ∇c) + µ 1 n 1 (1 − n 1 − a 1 n 2 ), x ∈ Ω, t > 0, (n 2 ) t + u · ∇n 2 = ∆n 2 − χ 2 ∇ · (n 2 ∇c) + µ 2 n 2 (1 − a 2 n 1 − n 2 ), x ∈ Ω, t > 0,under homogeneous Neumann boundary conditions in a bounded domain Ω ⊂ R 3 with smooth boundary. Many mathematicians study chemotaxis-fluid systems and two-species chemotaxis systems with competitive kinetics. Ho… Show more

“…The first theorem gives global existence and boundedness in under smallness conditions of the chemotactic effect and largeness conditions of the logistic power. This result provides some guide to methods and results for the 3‐dimensional Keller‐Segel‐Stokes system, which is the case that −( α n 1 + β n 2 ) c is replaced with − c + α n 1 + β n 2 in .…”

“…Before we go to the details of our analysis, let us point out that the global existence, boundedness and stabilization of (weak) solutions to the two-species chemotaxis-fluid system have also been established (see e.g. [2,5,6,12,19]).…”

“…On the other hand, in the case that n 2 = 0 and Ω ⊂ R 2 , global existence and boundedness of classical solutions to (1.1) have been attained ( [4]). Moreover, in the case that κ = 0 in (1.1), which namely means that the fourth equation in (1.1) is the Stokes equation, global existence and stabilization can be found in [2]; in the case that κ = 0 in (1.1) and that −(αn 1 + βn 2 )c is replaced with +αn 1 + βn 2 − c, global existence and boundedness of classical solutions to the Keller-Segel-Stokes system and their asymptotic behaviour are found in [3].…”
