Abstract
In this paper, we establish the existence and concentration of solutions of a class of nonlinear Schrödinger equation
where 2 < p < ∞, α 0 > 0, 0 < γ < 2. When the potential function V (x) decays at infinity like (1 + |x|)−α with 0 < α ≤ 2 and K(x) > 0 are permitted to be unbounded under some necessary restrictions, we will show that a positive H 1(ℝ2)-solution u ɛ exists if it is assumed that the corresponding ground energy function G(ξ) of nonlinear Schrödinger equation \(- \Delta u + V\left( \xi \right)u = K\left( \xi \right)\left| u \right|^{p - 2} ue^{\alpha _0 \left| u \right|^\gamma }\) has local minimum points. Furthermore, the concentration property of u ɛ is also established as ɛ tends to zero.
