Local asymptotics for singular solutions to critical Hartree equations

For $n\geqslant3$ and $0<α<n$, we study positive classical solutions of critical Hartree equations that blow up at the origin. For the global problem on $\mathbb R^n\setminus\{0\}$, with the Hartree potential integrated over $\mathbb R^n$, we prove that solutions in $L^p(\mathbb R^n)$, where $p=(n+α
