Abstract
In this paper, we prove the existence of at least two solutions to some semilinear elliptic equation defined in the whole euclidean space \( {\mathbb {R}}^2.\) The nonlinearity consists of two terms: one presents a singularity at the origin and the other has a doubly exponential behavior at infinity. This new exponential behavior is governed by a recently established weighted inequality of Trudinger–Moser type. A combination of perturbation arguments and variational tools is employed to obtain our multiplicity result.
