... ,n} into l disjoint groups. The goal of labelled counting is to establish a relation between the cardinality of the sets of hands and the cardinality of the decks. For example, when dealing with ... multiset of x-coordinates of points in A, andletπ y (A) denote the multiset of y-coordinates. We are now ready to state Theorem 5.1. For every cardinality l bet...

... set of vertices corresponds to replacing Tsaranov’s generators for vertices in this set with their inverses; so the Tsaranov group is an invariant of the switching class, that is, of the two-graph. Now ... vertex of valency 2. Let ≡ be the reflexive and transitive closure of ∼.Then an arbitrary permutation of the labels within any equivalence class of ≡ does not cha...

We conclude that T (D) is equicontinuous and then is relatively compact by the Arzela–Ascoli theorem. By applying the Schauder theorem, T has a fixed point...
