摘要
本文研究了具有加权测度dμ=e~(-φ)dv的H型群G上漂移Laplace算子-?_G+<▽_Gφ,▽_G(·)>的Dirichlet特征值问题,建立了该问题的Levitin-Parnovski型特征值不等式,推广包含了Ilias和Makhoul对Heisenberg群上次Laplace算子所获得的结果 (J. Geom. Anal.,2012, 22(1):206–222).
In this paper, we study the Dirichlet eigenvalue problem of the drifting Laplacian -?_G+<▽_Gφ,▽_G(·)>on the H-type group G with the weighted measured dμ = e~(-φ)dv. We establish a Levitin-Parnovski universal inequality for eigenvalues of this problem, which generalize the result derived by Ilias and Makhoul for the Kohn Laplacian on the Heisenberg group(J. Geom.Anal., 2012, 22(1): 206–222).
