A $C^0$-theory for the blow-up of second order elliptic equations of critical Sobolev growth
Olivier Druet, Emmanuel Hebey, and Frédéric Robert
Abstract.
Let $(M,g)$ be a smooth compact Riemannian manifold
of dimension $n \ge 3$, and $\Delta_g = -div_g\nabla$ the Laplace-Beltrami
operator. Also let $2^\star$ be the critical Sobolev exponent
for the embedding of the Sobolev space $H_1^2(M)$ into Lebesgue spaces,
and $h$ a smooth function on $M$.
Elliptic equations of critical Sobolev growth like
\[\Delta_gu + hu = u^{2^\star-1}\]
have been the target of investigation
for decades. A very nice $H_1^2$-theory for the
asymptotic behaviour of solutions of such an equation
is available since the 1980's.
In this announcement we present the $C^0$-theory we have recently developed.
Such a theory provides
sharp pointwise estimates for the asymptotic behaviour of solutions of the
above equation.
