... L∞ (R3 ) via Assumption 1 and ∆ua (x) ∈ L2 (R3 ). Similarly ua ∆V ∈ L2 (R3 ) since ua (x) ∈ L∞ (R3 ) and ∆V ∈ L2 (R3 ) (see the Remark after Assumption 2). For the second term in the right side of (2.16) we have ∇ua (x) ∈ L2 (R3 ) and ∇V ∈ L∞ (R3 ) due to Lemma 6 of the Appendix. Hence ∇V.∇ua ∈ L2 ...

(It may, of course, have several external forces acting on it, but I mean by Fi the vector sum of all the external forces acting on the ith particle.) It may also interact with the other particles in the system, and consequently it may h ...
