Positive multi-bump solutions for the Schrödinger equation with slow decaying competing potentials
We are concerned with the existence of multi-bump solutions to the following nonlinear Schrödinger equation with competing potentials V and Q, where , V and Q are radial functions having the following slow algebraic decay with , . By introducing a weighted norm and some delicate analysis, we construct infinitely many new positive multi-bump solutions for or . The maximum points of these bump solutions lie on the top and bottom circles of a cylinder near the infinity. This result complements and extends the existence results of multi-bump solutions in [2], [11] from to the slow decaying potentials case .
