Our results concern existence and strong localization in the spatial region in which the logistic nonlinearity cancels. This type of nonlinearity has applications in the nonlinear Schrodinger equation and the study of Bose–Einstein condensates. In this context, our analysis explains the fact that the ground state presents a strong localization in the spatial region in which the nonlinearity cancels.engjournal articlehttp://ejde.math.txstate.edu/restricted access517.9Ecuaciones diferenciales1202.07 Ecuaciones en Diferencias
