周期势的定能逆散射

Inverse Scattering at a Fixed Quasi-Energy for Potentials Periodic in Time

Ricardo Weder

摘要:

我们证明了在一个固定的准能量的散射矩阵唯一确定一个时间周期势,指数衰减到无穷远。我们考虑的潜力,为每个固定的时间属于空间中的$L^{3/2}$。指数3/2对于空间中势的奇异性是关键的。对于这个奇异类的潜力的结果是新的,即使在时间无关的情况下,它只知道有界指数下降的潜力。

英文摘要:

We prove that the scattering matrix at a fixed quasi--energy determines uniquely a time--periodic potential that decays exponentially at infinity. We consider potentials that for each fixed time belong to $L^{3/2}$ in space. The exponent 3/2 is critical for the singularities of the potential in space. For this singular class of potentials the result is new even in the time--independent case, where it was only known for bounded exponentially decreasing potentials.
