本文通过Dirichlet边界条件将一维分数阶薛定谔算子与截断Toeplitz矩阵联系起来,并利用Szegö强极限定理确定α稳定对称律下特征值乘积的渐近行为。

摘要:

将量子粒子限制在实线的紧致子区间内并施加Dirichlet边界条件,我们揭示了一维分数阶薛定谔算子与截断Toeplitz矩阵之间的联系。通过应用Szegö强极限定理,我们确定了$α$-稳定对称律下特征值乘积的渐近行为。本文的结果可应用于最近提出的一个模型,该模型描述在一维有界区间上跳跃的粒子,其跳跃概率由分数阶拉普拉斯算子的离散表示给出。

英文摘要:

Confining a quantum particle in a compact subinterval of the real line with Dirichlet boundary conditions, we identify the connection of the one-dimensional fractional Schrödinger operator with the truncated Toeplitz matrices. We determine the asymptotic behaviour of the product of eigenvalues for the $α$-stable symmetric laws by employing the Szegö's strong limit theorem. The results of the present work can be applied to a recently proposed model for a particle hopping on a bounded interval in one dimension whose hopping probability is given a discrete representation of the fractional Laplacian.
