论文摘要
Balcar，Pelant和Simon的经典定理说，有一个高度H的基本矩阵，其中H是P（Omega）/Fin的分布数。我们表明，如果连续c是规则的，则具有高度C的基本矩阵，并且在Cohen和随机模型中，有任何常规无数高度或等于C的基本矩阵。这回答了Fischer，Koelbing和Wohofsky的问题。
A classical theorem of Balcar, Pelant, and Simon says that there is a base matrix of height h, where h is the distributivity number of P(omega)/fin. We show that if the continuum c is regular, then there is a base matrix of height c, and that there are base matrices of any regular uncountable height less or equal than c in the Cohen and random models. This answers questions of Fischer, Koelbing, and Wohofsky.
