Popis: | In this paper we survey some results concerning the construction of spike-layers, namely solutions to singularly perturbed equations that exhibit a concentration behaviour. Their study is moti- vated by the analysis of pattern formation in biological systems such as the Keller-Segel or the Gierer- Meinhardt’s. We describe some general perturbative variational strategy useful to study concentration at points, and also at spheres in radially symmetric situations. |
