Abstract We prove a compactness criterion in L p ( μ , X ) : a subset of L p ( μ , X ) is relatively norm compact iff the set of integrals of its functions over any measurable set is relatively norm compact, it satisfies the Frechet oscillation restriction condition and it is p -uniformly integrable. The proof is elementary.

关于 Lp(μ,X) 中范数紧缩性的评论

摘要 我们证明了 L p ( μ , X ) 中的紧性准则: L p ( μ , X ) 的子集是相对范紧的,当当它的函数在任何可测集上的积分集是相对范紧的,它满足 Frechet振荡限制条件,它是 p 一致可积的​​。证明是基本的。
