摘要
我们发现了一种新的有限算法,用于在有限维无 Lipschitz p 空间中评估无 Lipschitz p 空间规范。我们用这个算法来处理给定 p 空间 \(\mathcal {N}\subset \mathcal {M},\) 的 \(\mathcal {F}_p(\mathcal {N})\) 的规范嵌入到 \(\mathcal {F}_p(\mathcal {M})\) 是否是同构的问题。这个方向上最重要的结果是,如果 \(\mathcal {N}\subset \mathcal {M}\) 都是度量空间,答案就是肯定的。
We find a new finite algorithm for evaluation of Lipschitz-free p-space norm in finite-dimensional Lipschitz-free p-spaces. We use this algorithm to deal with the problem of whether given p-metric spaces \(\mathcal {N}\subset \mathcal {M},\) the canonical embedding of \(\mathcal {F}_p(\mathcal {N})\) into \(\mathcal {F}_p(\mathcal {M})\) is an isomorphism. The most significant result in this direction is that the answer is positive if \(\mathcal {N}\subset \mathcal {M}\) are metric spaces.
