符号可变的Bargmann-Toeplitz算子的谱

On the spectrum of Bargmann-Toeplitz operators with symbols of a variable sign

Alexander Pushnitski, Grigori Rozenblum

摘要:

本文讨论了Bargmann空间中Toeplitz算子的谱。我们的Toeplitz算子具有带可变符号和紧支持的实数符号。一类的例子被认为是这样的运营商的特征值的渐近可以计算。这些例子表明,这种渐近性取决于符号的正负部分的支撑的几何形状。扰动朗道哈密顿量的应用。

英文摘要:

The paper discusses the spectrum of Toeplitz operators in Bargmann spaces. Our Toeplitz operators have real symbols with a variable sign and a compact support. A class of examples is considered where the asymptotics of the eigenvalues of such operators can be computed. These examples show that this asymptotics depends on the geometry of the supports of the positive and negative parts of the symbol. Applications to the perturbed Landau Hamiltonian are given.
