For a graph G and positive integers n and q, we ... the proof of Theorem 4 leaves a lot of room for improvement. For the sake of simplicity and clarity of the presentation, in Claim 9 and Lemma 10, we settled for bounds on deg M (v) and e (...

... only for t = o(n 1/5 ) (as provedin[9]), whilst for a ∆ inflated as in (10) and (11), the bound (5) is not useful, and, as we have seen, the extended Janson inequality unfortunately requires, for ... (see [9] for a proof). Now if one seeks to maximize ϕ (with ∆ as in (7)) for p =(t/ne) 2/t exp{(a n + log t)/t 2 }, where a n →∞at an arbitrarily slow rate, then the maximum is achieved,...
