Abstract

We consider a nonlinear reaction diffusion equation on the whole euclidean space. We prove the well-posedness of the corresponding Cauchy problem in a general functional setting, namely, when the initial datum is uniformly locally bounded in L2 only. Then we adapt the short trajectory method to establish the existence of the global attractor and, in the 3-dimensional case, we find an upper bound of its Kolmogorov epsilon-entropy.
