In this article, we consider the eigenvalue problem for the bi-Kohn Laplacian and obtain universal bounds on the (k + 1)-th eigenvalue in terms of the first k eigenvalues independent of the domains.
Let Ω be a connected bounded domain in R^n. Denote by λi the i-th eigenvalue of the Lapla^ian operator with any order p:{u=Эn→^-Эu=…=Эn→p-1^-Эp-1u=0 on ЭΩ (-△)pu=λu in Ω.In this article, we give som...Let Ω be a connected bounded domain in R^n.
