论文摘要
由Altshuler著名的单位矢量基础表征$ C_0 $或$ \ ELL_P $在对称基础中的动机，我们在民主基地和双方民主基础之间获得了类似的特征。我们还证明了$ \ ell_1 $的单位向量基础的单独表征。
Motivated by Altshuler's famous characterization of the unit vector basis of $c_0$ or $\ell_p$ among symmetric bases, we obtain similar characterizations among democratic bases and among bidemocratic bases. We also prove a separate characterization of the unit vector basis of $\ell_1$.
