离散麦克斯韦算子的谱分析:极限吸收原理

Spectral analysis of the discrete Maxwell operator: The limiting absorption principle

Olivier Poisson

AI总结:

本研究针对三维正方晶格上的各向异性离散麦克斯韦算子开展谱分析,通过构造对应非零实值的共轭算子证明其满足极限吸收原理,并证实特定阈值下共轭算子本质自伴。

摘要:

我们关注定义在正方形格点$\rm Z\\!\rm Z^3$上的各向异性离散麦克斯韦算子$\u0124^D$的谱分析。为证明其满足极限吸收原理,我们针对任意非零实值,构造了与$\u0124^D$的傅里叶级数共轭的算子。此外我们证明,在某些特定阈值处,该共轭算子本质上是自伴的。

英文摘要:

We are interested by the spectral analysis of the anisotropic discrete Maxwell operator $\hat H^D$ defined on the square lattice $\rm Z\!\!\! Z^3$. In aim to prove that the limiting absorption principle holds we construct a conjugate operator to the Fourier series of $\hat H^D$ at any not-zero real value. In addition we show that at some particular thresholds the conjugate operator is essentially self-adjoint.
