Abstract
We consider the following quasilinear attraction-repulsion chemotaxis system with rotation {ut=Îumâââ
(uS1(u,v,w,x)âv)+ââ
(uS2(u,v,w,x)âw),xâΩ,t>0,vt=Îv+αuâβv,xâΩ,t>0,wt=Îw+γuâδw,xâΩ,t>0,(âumâuS1âv+uS2âw)â
ν=âvâ
ν=âwâ
ν=0,xââΩ,t>0, where ΩâR2 is a bounded domain with smooth boundary and α, β, γ, δ are positive constants. Here S1=(sÌij)2Ã2 and S2=(sËij)2Ã2 are chemosensitivity tensors with sÌij,sËijâC2([0,â)3ÃΩÌ), which are assumed to satisfy |S1|â¤CS1 and |S2|â¤CS2 with some positive constants CS1, CS2 for all (u,v,w,x)â[0,â)3ÃΩÌ. It is shown that whenever m>1, for any sufficiently smooth non-negative initial data, the system possesses at least one global bounded weak solution.
