Sharp asymptotic profiles for singular solutions to an elliptic equation with a sign-changing nonlinearity

Florica C. Cîrstea, Frédéric Robert

Given $B_1(0)$ the unit ball of ${\mathbb{R}}^n$ ($n\ge 3$), we study smooth positive singular solutions $u\in C^2(B_1(0)\setminus \{0\})$ to $-Δu=\frac{u^{2^\star(s)-1}}{|x|^s}-μu^…
