Abstract:We prove that every isometry between two combinatorial spaces is determined by a permutation of the canonical unit basis combined with a change of signs. As a consequence, we show that in the case of Schreier spaces, all the isometries are given by a change of signs of the elements of the basis. Our results hold for both the real and the complex cases.

组合Banach空间的同义

摘要：我们证明了两个组合空间之间的每个等距都是由规范单位基础的排列结合符号的变化确定的。结果，我们表明在Schreier空间的情况下，所有等距都是通过基础元素符号的变化给出的。我们的结果适用于实际情况和复杂情况。
