希尔伯特空间上的时间分数阶薛定谔方程

The time fractional Schrödinger equation on Hilbert space

Przemysław Górka, Humberto Prado, Juan Trujillo

摘要:

研究了希尔伯特空间上的线性分数阶薛定谔方程,该方程具有$0<α<1,$阶分数阶时间导数和自伴生成元$A.$.利用谱定理证明了强解的存在唯一性,并证明了解受算子解族$\{U_α(t)\}_{t\geq 0}$的控制.证明了当$α$逼近$1$时,解族$U_α(t)$强收敛于酉算子族$e^{-itA},$.

英文摘要:

We study the linear fractional Schrödinger equation on a Hilbert space, with a fractional time derivative of order $0<α<1,$ and a self-adjoint generator $A.$ Using the spectral theorem we prove existence and uniqueness of strong solutions, and we show that the solutions are governed by an operator solution family $\{U_α(t)\}_{t\geq 0}$. Moreover, we prove that the solution family $U_α(t)$ converges strongly to the family of unitary operators $e^{-itA},$ as $α$ approaches to $1$.
