On the global bifurcation diagram of the equation $- Δ u = μ ∣ x ∣^{2 α} e^{u}$ in dimension two

Daniele Bartolucci, Aleks Jevnikar, Ruijun Wu

The aim of this note is to present the first qualitative global bifurcation diagram of the equation $- Δ u = μ ∣ x ∣^{2 α} e^{u}$ . To this end, we introduce the notion of domains of first/sec…

A Courant nodal domain theorem for linearized mean field type equations

Daniele Bartolucci, Aleks Jevnikar, Ruijun Wu

We are concerned with the analysis of a mean field type equation and its linearization, which is a nonlocal operator, for which we estimate the number of nodal domains for the radi…
