چکیده انگلیسی
This paper deals with the parabolic-elliptic-elliptic attraction-repulsion chemotaxis system with logistic source{ut=ââ
(D(u)âu)âââ
(Ïuâv)+ââ
(ξuâw)+ruâμu2,xâΩ,t>0,0=Îv+αuâβv,xâΩ,t>0,0=Îw+γuâδw,xâΩ,t>0, under no-flux boundary conditions in bounded domain with smooth boundary, where Ï,ξ,α,β,γ,δ,r and μ are assumed to be positive. When ΩâR3, D(u) is assumed to satisfy D(0)>0,D(u)â¥cDumâ1withmâ¥1andcD>0, it is proved that if Ïαâξγ>0 and μ=13(Ïαâξγ), then for any given u0âW1,â(Ω), the system possesses a global and bounded classical solution. For the case where D(u)â¡1 and nâ¥3, the convergence rate of the solution is established. When the random motion of the chemotactic species is neglected i.e. (D(u)â¡0) and ΩâRn(nâ¥2) is a convex domain, boundedness and the finite time blow up of the solution are investigated.
