本文研究了二维格鲁伯-皮塔耶夫斯基模型中具有沿闭合曲线定向集中现象的解,通过构造特定频率序列得到解,并部分回答了关于子流形上解集中必要条件的猜想。

摘要:

我们研究了在单位质量约束下,带有陷阱势的二维格鲁伯-皮塔耶夫斯基方程的驻波解,其频率为λ,用于描述具有吸引力相互作用的玻色-爱因斯坦凝聚体。首先,我们研究了存在具有沿闭合光滑曲线定向集中现象的解的必要条件。接下来,不仅对曲线施加静止和非退化条件,相对于一个辅助加权长度涉及陷阱势,而且添加一些其他技术假设,我们选择一个频率λ的序列{λ_j},使得-λ_j→+∞,并构造沿曲线定向的解。我们的结果部分回答了[A. Ambrosetti, A. Malchiodi, W.-M. Ni, Comm. Math. Phys. 2003]中关于解在子流形上集中必要条件的猜想。本文构造的解在长度非均匀有界的曲线上集中,因此情况与[M. del Pino, M. Kowalczyk, J. Wei, Comm. Pure Appl. Math. 2007]中的情况有很大不同。

英文摘要:

We concern standing wave solutions with frequency $λ$ to a two dimensional Gross-Pitaevskii equation with a trap potential under the unit mass constraint, which is used to describe Bose-Einstein condensates with attractive interaction. First, we investigate the necessary conditions for existence of the solutions with concentration phenomena directed along closed smooth curves. Next, not only imposing stationary and non-degeneracy conditions on the curves with respect to an auxiliary weighted length involving the trap potential, but also adding some other technical assumptions, we select a sequence $\{λ_j\}$ of the frequency $λ$ with $-λ_j\rightarrow +\infty$ and construct solutions with concentration directed along the curves. Our result partially answers the conjecture raised in [A. Ambrosetti, A. Malchiodi, W.-M. Ni, Comm. Math. Phys. 2003] about necessary condition for solution concentrating at submanifolds. The solutions constructed in this paper are concentrating on curves whose length are non-uniformly bounded, and hence the situation is quite different from that in [M. del Pino, M. Kowalczyk, J. Wei, Comm. Pure Appl. Math. 2007].
