Abstract We look for positive solutions to the nonlinear Schrödinger equation −Ɛ2∆u − V (x)f′(u) = 0 in ℝN, where V is a continuous bounded positive potential and f satisfies particular growth conditions which make our problem fall in the so called “zero mass case”. We prove an existence result for any Ɛ > 0, and a multiplicity result for Ɛ sufficiently small.
