... ⊆  [n] r  k-wise intersecting if for any F 1 , . . . , F k ∈ F,  k i=1 F i = ∅. Frankl [5] proved the following theorem for k-wise intersecting families. Theorem 1.1 (Frankl). Let F ⊆  [n] r  be k-wise ... ǫ)  n−1 r−1  . We note that for k ≥ 2, F is k-wise intersecting implies that it is intersecting. Hence if r < n/2, the results obtained in the papers mention...

... →∞,h(x i )→H(2p i − p 2 i ). Therefore we have [2α − β(p)+o(1)]n ≤ n  i=1 H(2p i − p 2 i ) ≤ nφ(p) (since pn =  p i ). Therefore αn ≤ 1 2 [β(p)+φ(p)+o(1)]n.
