Title: Energy quantization for Yamabe's problem in conformal dimension

Abstract: 
 Riviere [11] proved an energy quantization for
 Yang-Mills fields defined on $n$-dimensional Riemannian manifolds,
 when $n$ is larger than the critical dimension 4. More precisely,
 he proved that the defect measure of a weakly converging sequence
 of Yang-Mills fields is quantized, provided the $W^{2,1}$ norm
 of their curvature is uniformly bounded. In the present paper,
 we prove a similar quantization phenomenon for the nonlinear
 elliptic equation
 $$
 - \Delta{u}= u  |u|^{4/(n-2)},
 $$
 in  a subset $\Omega$ of $\mathbb{R}^n$.
