球面中具有常平均曲率超曲面的谱特征(英文)
The Spectral Characterizations of Hypersurfaces in a Sphere
【摘要】 本文中,我们研究了一类schrodinger算子的第一特征值,给出了Sn+1中一类常平均曲率超曲面的特征,并得到了这种超曲面的谱几何,从而推广了第二作者的有关结果.
【Abstract】 In this paper, we study eigenvalues of a Schrodinger operator related to the second fundamental form of a hypersurface in a sphere, from which we obtain a new characterization of the hypersurface as well as its spectral geometry. This generalizes a result of the second author.
