Abstract
Consider the bi-harmonic differential expression of the form A = 2M2 + q on a manifold of bounded geometry (M, g) with metric g, where M is the scalar Laplacian on M and q ≥ 0 is a locally integrable function on M. In the terminology of Everitt and Giertz, the differential expression A is said to be separated in Lp (M), if for all u ∈ Lp (M) such that Au ∈ Lp (M), we have qu ∈ Lp (M). In this paper, we give sufficient conditions for A to be separated in Lp (M),where 1 < p < ∞
