Piero D'Ancona, Luca Fanelli, Luis Vega, Nicola Visciglia

摘要:

我们证明Schroedinger方程的电磁势,在尺寸$n\geq3$的Schroedinger方程的Schroedinger估计。对势的衰减和规则性假设几乎是关键的,即,与库仑案很接近此外,我们需要排斥性和非捕获条件,它们表示为势的合适分量的小。然而,潜力本身可以很大,我们完全避免任何先验谱假设的运营商。证明是基于平滑估计和新的Sobolev嵌入空间与磁势。

英文摘要:

We prove Strichartz estimates for the Schroedinger equation with an electromagnetic potential, in dimension $n\geq3$. The decay and regularity assumptions on the potentials are almost critical, i.e., close to the Coulomb case. In addition, we require repulsivity and a non trapping condition, which are expressed as smallness of suitable components of the potentials. However, the potentials themselves can be large, and we avoid completely any a priori spectral assumption on the operator. The proof is based on smoothing estimates and new Sobolev embeddings for spaces associated to magnetic potentials.
