The existence or not of a neighbourhood of zero where the problems are linear has an influence on the methods used and on the dynamics of the induced skew-product semiflow. That is why two cases are distinguished: linear-dissipative and purely dissipative problems. In both cases, the structure of the global and pullback attractors is studied using principal spectral theory. Besides, in the purely dissipative setting, a simple condition is given, involving both the underlying linear dynamics and some properties of the nonlinear term, to determine the nontrivial sections of the attractor PB Elsevier SN 0022-0396 YR 2021 FD 2021 LK https://uvadoc.uva.es/handle/10324/58612 UL https://uvadoc.uva.es/handle/10324/58612 LA eng NO Journal of Differential Equations, 2021, vol. 285, p. 714–750 NO Producción Científica DS UVaDOC RD 27-dic-2024
