摘要:

本文从描述气体相互作用玻色子的$N$ -体薛定谔方程出发,在极限$N\rightarrow\infty$下,导出了三维$d=3$中的散焦Gross-Pitaevskii(GP)族.本文的主要结果是证明了相应的BBGKY族收敛到GP族的空间中介绍了我们以前的工作的柯西问题的适定性GP族,\cite{chpa2,chpa3,chpa4},这是由Klainerman和Machedon在\cite{klma}中介绍的时空范数的基础上的解决方案空间的启发。我们注意到,在$d=3$中,这是该领域中众所周知的开放问题。虽然我们的结果不假设因式分解的解决方案,考虑因式分解的解决方案产生一个新的推导立方,散焦非线性薛定谔方程(NLS)在$d=3$。

英文摘要:

We derive the defocusing cubic Gross-Pitaevskii (GP) hierarchy in dimension $d=3$, from an $N$-body Schrödinger equation describing a gas of interacting bosons in the GP scaling, in the limit $N\rightarrow\infty$. The main result of this paper is the proof of convergence of the corresponding BBGKY hierarchy to a GP hierarchy in the spaces introduced in our previous work on the well-posedness of the Cauchy problem for GP hierarchies, \cite{chpa2,chpa3,chpa4}, which are inspired by the solutions spaces based on space-time norms introduced by Klainerman and Machedon in \cite{klma}. We note that in $d=3$, this has been a well-known open problem in the field. While our results do not assume factorization of the solutions, consideration of factorized solutions yields a new derivation of the cubic, defocusing nonlinear Schrödinger equation (NLS) in $d=3$.
