In particular, we investigate reaction\u2013diffusion equations with almost-periodic coefficients. The associated semiflows are strongly monotone which allow us to give a full characterization of the cocycle attractor. We prove that, when the upper Lyapunov exponent associated to the linear part of the equations is positive, the flow is persistent in the positive cone, and we study the stability and the set of continuity points of the section of each minimal set in the global attractor for the skew product semiflow. We illustrate our result with some nontrivial examples showing the richness of the dynamics on this attractor, which in some situations shows internal chaotic dynamics in the Li\u2013Yorke sense. We also include the sublinear and concave cases in order to go further in the characterization of the attractors, including, for instance, a nonautonomous version of the Chafee\u2013Infante equation. In this last case we can show exponentially forward attraction to the cocycle (pullback) attractors in the positive cone of solutions. <\/jats:p>","DOI":"10.1142\/s0218127416501352","type":"journal-article","created":{"date-parts":[[2016,8,5]],"date-time":"2016-08-05T05:03:24Z","timestamp":1470373404000},"page":"1650135","source":"Crossref","is-referenced-by-count":3,"title":["Characterization of Cocycle Attractors for Nonautonomous Reaction\u2013Diffusion Equations"],"prefix":"10.1142","volume":"26","author":[{"given":"C.
