Corrigendum to ‘Algebraic characterizations of regularity
The authors regret a flaw in the proof of a result in our paper [1] cited in the title. They would like to apologize for any inconvenience caused. This corrigendum provides corrected statements and proofs of such a result. (For theoretical background on the subject, see, for instance, Cvetković, Doob, and Sachs [5], Biggs [2], Brouwer, Cohen, and Neumaier [3], Brouwer and Haemers [4], Van Dam, ...
متن کاملCorrigendum Corrigendum to “ Saturated simplicial complexes ” [ J . Combin
One of the main results in the paper of the title is potentially incorrect as stated. To correct the statement the notion of the link of a subcomplex in a simplicial complex is required, and this is more general than the usual definition of link. This new definition is given here and it is shown that it indeed gives the required theorem. The aim of the paper in the title is to provide a local c...

1. In Definition 2.4, ‘‘(iv) {0} = g(r i−1 1 , 0, r n−1 i+1 , x)’’. 2. In Definition 2.5, ‘‘g(R(n−1),N) ∈ P (N)’’. 3. Page 5, line 1, ‘‘0 ∈ g(0, 1 R ,m) ⊆ g(R, 1 (n−2) R ,m)’’. 4. Page 6, line 4, ‘‘f (x1 ) = h(x m 1 ) = m i=1 xi = m i=1 xi =’’. 5. Page 7, Lemma 3.7 is not true (is removed) and XP(M) is not a subhypermodule ofM . Hence, we define the set XP(M) accompany with XP(M) and consider...

متن کاملCharacterizations of bipartite Steinhaus graphs
We characterize bipartite Steinhaus graphs in three ways by partitioning them into four classes and we describe the color sets for each of these classes. An interesting recursion had previously been given for the number of bipartite Steinhaus graphs and we give two fascinating closed forms for this recursion. Also, we exhibit a lower bound, which is achieved infinitely often, for the number of ...
