摘要: 该文研究Heisenberg群上Folland-Stein算子Lα(α为复数)的特征值问题,证明了当|Reα|<n时,Lα具离散分布的特征值.当α∈(-n,n)时,特征值均为正的.然后给出了相邻特征值之差的估计.

Abstract: We study the Dirichlet eigenvalue problem of the Folland-Stein operator Lα which has discrete eigenvalues as|Reα|<n and positive eigenvalues as α∈(-n,n). Then by establishing the Rayleigh Theorem and the Min-Max Theorem we give the estimates for the differences of the consecutive eigenvalues.

Key words: Folland-Stein operator, eigenvalue, estimate
