Abstract:

Let $\Sigma$ be a smooth compact connected surface of $*R*^3$ without boundary and denote by $A$ its second fundamental. In a previous paper we proved that, if $\ A- ({\rm tr } A/2) {\rm Id}\ _{L^2 (\Sigma)}$ is small, then $\Sigma$ is $W^{2,2}$--close to a round sphere. In this note we show that, in addition, the metric of $\Sigma$ is $C^0$--close to the standard metric of $*S*^2$.
