“…In the case where ( ) ≡ 0, = = 0, (1) becomes the normal plate equation which has been treated in many papers such as [7][8][9][10][11][12][13][14]. For instance, the authors investigated the existence of the compact attractor for the plate equation on both the bounded domain [8,10,13] and the unbounded domain in [7,11,12], respectively.…”
