“…In ruling out the possibility of a vanishing weak limit, we exploit the growth conditions assumed on f , namely f (t) = O(|t| p−1 ) as t → ∞ and f (t) = O(|t| q−1 ) as t → 0 where p and q are subcritical and supercritical exponents respectively (see hypothesis (f 1 )). Probably these conditions were first considered in [14]. More recently, they have also been used in [5], [9], [10], [11], [12], [29].…”
