Abstract: In this paper we deal with the following class of nonlinear Schrödinger equations −Δu+V(|x|)u=λQ(|x|)f(u),x∈R2, where λ>0 is a real parameter, the potential V and the weight Q are radial, which can be singular at the origin, unbounded or decaying at infinity and the nonlinearity f(s) behaves like eαs2 at infinity. By performing a variational approach based on a weighted Trudinger–Moser type inequality proved here, we obtain some existence and multiplicity results.
Keywords: Nonlinear Schrödinger equation, unbounded or decaying radial potentials, exponential critical growth, weighted Trudinger–Moser type inequality
