Also, we give some motivations about how the theorems are constructed. In the final section, we discuss the future works of Gross-Pitaevskii equation.1051869 bytesapplication/pdf論文公開時間: 2015/8/20論文使用權限: 同意無償授權行波解Gross-PitaevskiiTraveling Wavesthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/276775/1/ntu-104-R01221038-1.pdf
