The class of submanifolds $M$ with $a(M)<1$ contains all complete minimal surfaces in $\mathbb{R}^{n}$ with finite total curvature, all $m$-dimensional minimal submanifolds $M $ of $ \mathbb{R}^{n}$ with finite total scalar curvature $\smallint_{M}| α|^{m} dV<\infty $ and all complete 2-dimensional complete surfaces with $\smallint_{M}| α|^{2} dV<\infty $ and nonpositive curvature with respect to every normal direction, since $a(M)=0$ for them.8 pagesDifferential Geometry53C42text
