The aim of this note is to present the first qualitative global bifurcation diagram of the equation −∆u = µ|x|2αeu. To this end, we introduce the notion of domains of first/second kind for singular mean field equations and base our approach on a suitable spectral analysis. In particular, we treat also non-radial solutions and non-symmetric domains and show that the shape of the branch of solutions still resembles the well-known one of the model regular radial case on the disk. Some work is devoted also to the asymptotic profile for µ → −∞.

Abstract
The aim of this note is to present the first qualitative global bifurcation diagram of the equation −∆u = µ|x|2αeu. To this end, we introduce the notion of domains of first/second kind for singular mean field equations and base our approach on a suitable spectral analysis. In particular, we treat also non-radial solutions and non-symmetric domains and show that the shape of the branch of solutions still resembles the well-known one of the model regular radial case on the disk. Some work is devoted also to the asymptotic profile for µ → −∞.File in questo prodotto:
