“…According to the proof of Step 1, we know that {Q n1 u n ; n ≥ 1}| h,t 2 , {Q F1 u n ; n ≥ 1}| h,t 2 , {Q n4 u n ; n ≥ 1}| h,t 2 3.39 are all precompact in PC h, t 2 , X and Q F2 : PC h, t 2 , X → PC h, t 2 , X is Lipschitz continuous with constant M 0 L LC 1−β K β /β. Next, we will show that {Q n2 u n ; n ≥ 1}| h,t 2 is precompact in PC h, t 2 , X .…”
