与Farey分数相关的转移算子的谱分析
Spectral analysis of transfer operators associated to Farey fractions
摘要:
本文详细研究了与Farey映射相关联的单参数符号迁移算子族的谱。我们证明了当作用在一个合适的解析函数的Hilbert空间上时,它们是自伴的,并且表现出绝对的连续谱,没有非零点谱。讨论了参数为负半整数时的多项式本征函数。
英文摘要:
The spectrum of a one-parameter family of signed transfer operators associated to the Farey map is studied in detail. We show that when acting on a suitable Hilbert space of analytic functions they are self-adjoint and exhibit absolutely continuous spectrum and no non-zero point spectrum. Polynomial eigenfunctions when the parameter is a negative half-integer are also discussed.
