闭凸集半群中的序消去律

Order Cancellation Law in a Semigroup of Closed Convex Sets

Jerzy Grzybowski, Hubert Przybycien

AI总结:

该研究推广了向量空间子集的序消去律,引入弱窄集概念并证明相关消去律,还将满足条件的闭凸集半群拓扑嵌入拓扑向量空间,拓展了相关经典定理。

摘要:

本文推广了Robinson提出的向量空间子集序消去律版本,该版本中我们通过无界集进行消去。我们引入了赋范空间中弱窄集的概念,研究了其性质,并证明了当被消去集为弱窄集时的序消去律。此外,我们还证明了拓扑向量空间中闭凸子集的序消去律,其中被消去集与其回收锥之间具有有界的类Hausdorff距离。我们将共享同一个回收锥、且与该回收锥的类Hausdorff距离有界的闭凸集构成的半群,拓扑嵌入到一个拓扑向量空间中。该结果推广了Bielawski和Tabor对Radstrom定理的推广结论。

英文摘要:

In this paper generalize Robinson's version of an order cancellation law for subsets of vector spaces in which we cancel by unbounded sets. We introduce the notion of weakly narrow sets in normed spaces, study their properties and prove the order cancellation law where the canceled set is weakly narrow. Also we prove the order cancellation law for closed convex subsets of topological vector space where the canceled set has bounded Hausdorff-like distance from its recession cone. We topologically embed the semigroup of closed convex sets sharing a recession cone having bounded Hausdorff-like distance from it into a topological vector space. This result extends Bielawski and Tabor's generalization of Radstrom theorem.
