Abstract We investigate the spectrum of the Lax operator L u of the Benjamin-Ono equation on the torus for complex valued potentials u in the Sobolev space H − s ( T , C ) , 0 ≤ s 1 / 2 , with small imaginary part and prove analytic properties of the moment map, defined in terms of spectral data of L u .

关于圆环上 Benjamin-Ono 方程的 Lax 算子的谱

摘要 我们研究了 Sobolev 空间 H − s ( T , C ) , 0 ≤ s 1 / 2 中的复值势 u 的环面上 Benjamin-Ono 方程的 Lax 算子 L u 的谱,其虚部很小,并且证明矩图的解析性质,根据 L u 的谱数据定义。
