Abstract
We consider the existence of a positive (generally unbounded) solution to the semilinear Schrödinger equation in a two-dimensional exterior domain. Our method relies on the comparison method, that is, the technique of super/sub-solutions. An application to Emden-Fowler equation is also presented.
