New type of solutions for the critical Lane-Emden system

In this paper, we consider the critical Lane-Emden system \begin{align*} \begin{cases} -Δu=K_1(y)v^p,\quad y\in $\mathbb{R}$^N,&\ -Δv=K_2(y)u^q,\quad y\in $\mathbb{R}$^N,&\ u,v>0, \end{cases} \end{align*} where $N\ge 5$, $p,q\in (1,\mathrm{\infty })$ with $\frac{1}{p+1}+\frac{1}{q+1}=\frac{N-2}{N}$, $K_1(y)$ and $K_2(y)$ are positive radial potentials. Under suitable conditions on $K_1(y)$ and $K_2(y)$, we construct a new family of solutions to this system, which are centred at points lying on the top and the bottom circles of a cylinder.
