C-spaces and matrix of infinite-dimensionality

We investigate classes (m,n)-C which are intermediate between the class S-wid of weakly infinite-dimensional spaces in the sense of Smirnov and the class S-∞-C of finite C-spaces in the sense of Borst. We find relationships between classes (m1,n1)-C and (m2,n2)-C. It allows us to construct a matrix of infinite-dimensionality.
