研究了高维Benjamin-Ono方程的初值问题。我们的目的是建立加权Sobolev空间中的局部适定性结果,并根据它们确定解流的一些尖锐的唯一连续性质。因此,确定了该模型的最佳衰减率。一个关键的组成部分是推导一个新的换向器估计涉及Riesz变换。
We study the initial value problem associated to a higher dimensional version of the Benjamin-Ono equation. Our purpose is to establish local well-posedness results in weighted Sobolev spaces and to determinate according to them some sharp unique continuation properties of the solution flow. In consequence, optimal decay rate for this model is determined. A key ingredient is the deduction of a new commutator estimate involving Riesz transforms.
