Thus by the separability of E,thespaceE ∗ is also separable ... a little more information of τ(E ∗ , E). Lemma 2.1. Let S be a total subset of E ∗ . Then there exists a sequence (x ∗ n ) of S such that the countable collection D of all linear co...

... r,theni and j are in the same block of π(Y ). Therefore, each C i is a block of π(h σ ). Then dim(h σ ) is the number of blocks of π(h σ ) and the number of cycles of σ. For example, if σ =(1, 2, ... then the character of the action of a group G on the homology of Q is (−1) r times the M¨obius function of the poset. Note that in many papers, the dimension of the homology...

The proof of this lemma has the same basic structure as that of Lemma 8, but the cycles we consider ... color of this chord. On the one hand, it must agree with one of the other edges of the n-cycle to avoid a rainbow n-cycle; on the other hand, it must similarly agree with one...
