摘要
We consider L-2-constraint minimizers of the Choquard energy functional with a trapping potential V(x) = |x|(2). It is known that positive minimizers exist if and only if the parameter a satisfies a < a* := ||Q||(2)(2), where Q is the unique positive radial solution of -Delta u + u - |u|(4/3) u = 0 in R-3. This paper focuses on the local uniqueness of minimizers by using energy estimates, blow-up analysis and establishing the Pohozaev identity.
