Salem Eljazi, Najoua Gamara, Habiba Guemri

摘要:

本文利用关于里奇曲率和直径的条件,给出了紧致黎曼流形的共形Laplacian算子和Yamabe不变量的第一特征值的界,并导出了流形共形于球面的某些条件.

英文摘要:

In this paper we give bounds for the first eigenvalue of the conformal Laplacian and the Yamabe invariant of a compact Riemannian manifold, by using conditions on the Ricci curvature and the diameter and deduce certain conditions on the manifold to be conformal to a sphere.
