Query: A global pinching theorem of complete $\lambda$-hypersurfaces   In this paper, the pinching problems of complete $\lambda$-hypersurfaces in a
Euclidean space $\mathbb R^{n+1}$ are studied. By making use of the Sobolev
inequality, we prove a global pinching theorem of complete
$\lambda$-hypersurfaces in a Euclidean space $\mathbb R^{n+1}$.
