- We focus on the classification of positive solutions to $(-Δ)^s u=\frac{x_n^α}{u^γ}$ in the half space with $γ>0$, subject to the Dirichlet condition. We show that when $-2s<α<(γ-1)s$, all positive solutions exhibit one-dimensional symmetry and are monotone increasing in $x_n$. Moreover, we provide a complete classification of all such one-dimensional solutions via their ``asymptotic $s$-order slope". When $α$ lies outside this range, we demonstrate the nonexistence of global positive solutions.
