摘要:

该文利用伸缩变换结合重排不等式等技巧得到了修正Gross-Pitaevskii方程对应极小化问题极小元的存在性与非线性项指数p的依赖关系.当0p2+4N时,对任意c>0 ,极小化问题存在极小元.若p=2+4Ncϕ2或者c>(32)N4ϕ2(ϕ2的定义见第一节)或p>2+4N ,问题不存在极小解.而对于p=2+4Nϕ2c(32)N4ϕ2 ,不知道是否存在极小解.

Abstract:

In this paper, using scaling technique and some rearrangement inequalities, existence and classification of ground states for a class of Modified Gross-Pitaevskii equations with respect to the nonlinear exponent p. If 2p2+4N , for any c>0 , there is at least a minimizer for this problem. If p=2+4N and cϕ2 or c>(32)N4ϕ2 (the definition of ϕ2 see section 1) or p>2+4N , there is no minimizer for this problem. But it is unclear if p=2+4N and ϕ2c(32)N4ϕ2.

Key words: Modified Gross-Pitaevskii equation, Ground state, Existence
