Positive and nodal solutions for the Minkowski mean curvature equation: multiplicity and asymptotics

Alberto Boscaggin, Francesca Colasuonno, Ricardo Ziegele

We consider the Dirichlet problem for the mean curvature operator in Minkowski space, \[ -\operatorname{div}\left(\frac{\nabla u}{\sqrt{1-|\nabla u|^2}}\right) = Î»u + Î¼h(x,u) \qu…

An Orlicz space approach to exponential elliptic problems in higher dimensions

Alberto Boscaggin, Francesca Colasuonno, Benedetta Noris +1

We consider semilinear elliptic problems of the form \[ -Îu + Î»u = f(x,u), \quad u\in H^1_0(A), \] where $A \subset R^{N}$ , $N \geq 3$ , is either a bounded or unbounded annulu…
