Multiple positive solutions to elliptic boundary blow-up problems

Alberto Boscaggin, Walter Dambrosio, Duccio Papini

We prove the existence of multiple positive radial solutions to the sign-indefinite elliptic boundary blow-up problem \[ \left\{\begin{array}{ll} Δu + \bigl(a^+(\vert x \vert) - μa…

Highly oscillatory solutions of a Neumann problem for a $p$ -laplacian equation

Alberto Boscaggin, Walter Dambrosio

We deal with a boundary value problem of the form $- ε (ϕ_{p} (ε u^{'}))^{'} + a (x) W^{'} (u) = 0, u^{'} (0) = 0 = u^{'} (1),$ where $ϕ_{p} (s) = ∣ s ∣^{p - 2} s$ for $s \in R$ and $p > 1$ , and $W:[…

Linear and nonlinear eigenvalue problems for Dirac systems in unbounded domains

Anna Capietto, Walter Dambrosio, Duccio Papini

We first study the linear eigenvalue problem for a planar Dirac system in the open half-line and describe the nodal properties of its solution by means of the rotation number. We t…
