Perturbation Methods and Semilinear Elliptic Problems on Rn By Antonio AmbrosettiEnglish | PDF | 2006 | 187 Pages | ISBN : 3764373210 | 1.81 MB
The aim of this monograph is to discuss several elliptic problems on Rn with two main features: they are variational and perturbative in nature, and standard tools of nonlinear analysis based on compactness arguments cannot be used in general. For these problems, a more specific approach that takes advantage of such a perturbative setting seems to be the most appropriate.
