We consider the two-species-two-chemical chemotaxis system
$\left\{ \begin{array}{l}{u_t}\; = \Delta u - {\chi _1}\nabla \cdot (u\nabla v) + {\mu _1}u(1 - u - {a_1}w),\;\;\;\;\;\;\;x \in \Omega ,t > 0,\\{u_t}\; = \Delta v - v + w,\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;x \in \Omega ,t > 0,\\{w_t}\; = \Delta w - {\chi _2}\nabla \cdot (w\nabla z) + {\mu _2}w(1 - w - {a_2}u),\;\;\;x \in \Omega ,t > 0,\\{z_t}\; = \Delta z - z + u,\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;x \in \Omega ,t > 0,\end{array} \right.$
where
$Ω\subset\mathbb{R}^n$
is a bounded domain with smooth boundary. The system models Lotka-Volterra competition of two species coupled with an additional chemotactic influence. In this model each species is attracted by the signal produced by the other.
We firstly show that if
$n=2$
and the parameters in the system above are positive, the solution to the corresponding Neumann initial-boundary value problem, emanating from appropriately regular and nonnegative initial data, is global and bounded.
Furthermore, we prove asymptotic stabilization of arbitrary global bounded solutions for any
$n≥q2$
, in the sense that:
• If
$a_1<1$
,
$a_2<1$
and both
$\frac{μ_1}{χ_1^2}$
and
$\frac{μ_2}{χ_2^2}$
are sufficiently large, then any global solution satisfying
$u\not\equiv0\not\equiv w$
converges towards the unique positive spatially homogeneous equilibrium of the system given above.
and
• If
$a_1≥q 1$
,
$a_2<1$
and
$\frac{μ_2}{χ_2^2}$
is sufficiently large any global solution satisfying
$w\not\equiv0$
tends to
$(0,1,1,0)$
as
$t\to∞$
.
Keywords: Multi-species chemotaxis, boundedness, logistic source, Lotka-Volterra competition, stability.
