Multiple nonsymmetric nodal solutions for quasilinear Schr\"{o}dinger system

In this paper, we consider the quasilinear Schr\"{o}dinger system in $\mathbb R^{N}$($N\geq3$): $$\left\{\begin{align} &-\Delta u+ A(x)u-\frac{1}{2}\triangle(u^{2})u=\frac{2\alpha }{\alpha+\beta}|u|^{\alpha-2}u|v|^{\beta},\\ &-\Delta v+ Bv-\frac{1}{2}\triangle(v^{2})v=\frac{2\beta }{\alpha+\beta}|u|^{\alpha}|v|^{\beta-2}v,\end{align}\right.$$ where $\alpha,\beta>1$, $2<\alpha+\beta<\frac{4N}{N-2}$,$B>0$ is a constant. By using a constrained minimization on Nehari-Poho\v{z}aev set, for any given integer $s\geq2$, we construct a non-radially symmetrical nodal solution with its $2s$ nodal domains.
