摘要
摘要研究了当0 < p < q≤∞时，嵌入算子h: h p(E)“h q(E)”的连续性。在[10]中已经描述了其充要条件。在这项工作中，我们使用一种新的方法解决了p = 1时的问题，但提出了一些关于Hermite-Biehler函数e的额外假设。
Abstract In this paper we study the continuity of the embedding operator ℓ : ℋp(E) ↪ ℋ q(E) when 0 < p < q ⩽ ∞. The necessary and sufficient condition has already been described in [10] if p > 1. In this work, we address the problem when p = 1, using a new approach, but asking some additional hypothesis about the Hermite-Biehler function E. We give also a different proof for the case p > 1.
