Abstract
In this paper, we are concerned with the following mixed-order conformally invariant system with coupled nonlinearity in \({\mathbb {R}}^{2}\):
where \(0\le p_1 < \frac{1}{1+K}\), \( p_2 >0\), \(q_1 >0\), \(q_2 \ge 0\), \(u>0\) and satisfies \(\int _{{\mathbb {R}}^{2}}u^{p_2}(x)e^{q_2 v(x)}dx<+\infty \). Under the assumptions, \(u(x)=O(|x|^{K})\) at \(\infty \) for some \(K\ge 1\) arbitrarily large and \(v^{+}(x)=O(\ln |x|)\) if \(q_2>0\) at \(\infty .\) We firstly derived the equivalent integral representation formula for (0.1). Then we discuss the exact asymptotic behavior of the solutions to system (0.1) as \(|x|\rightarrow \infty \). At last, by using the method of moving spheres in integral form, we give the classification of the classical solutions to (0.1).
