正则图的热核与广义Ihara zeta函数公式

Heat kernels on regular graphs and generalized Ihara zeta function formulas

Gautam Chinta, Jay Jorgenson, Anders Karlsson

摘要:

利用经典的I-Bessel函数建立了正则树上热核的一个新公式。虽然公式是显式的,并通过直接计算给出了证明,我们也提供了一个概念性的观点,使用正则树上的horocyclic变换。通过周期化,我们得到了任意正则图的热核表达式。从谱理论出发,我们得到了热核的另一种表达式,它是谱测度的积分变换。通过将这两个公式等价化,并进行一定的积分变换,得到了有限或无限正则图的Ihara zeta函数行列式公式的几个推广形式.我们的方法,伊原zeta函数和行列式公式,通过热核分析遵循一个类似的方法,存在于秩一对称空间的导数。

英文摘要:

We establish a new formula for the heat kernel on regular trees in terms of classical I-Bessel functions. Although the formula is explicit, and a proof is given through direct computation, we also provide a conceptual viewpoint using the horocyclic transform on regular trees. From periodization, we then obtain a heat kernel expression on any regular graph. From spectral theory, one has another expression for the heat kernel as an integral transform of the spectral measure. By equating these two formulas and taking a certain integral transform, we obtain several generalized versions of the determinant formula for the Ihara zeta function associated to finite or infinite regular graphs. Our approach to the Ihara zeta function and determinant formula through heat kernel analysis follows a similar methodology which exists for quotients of rank one symmetric spaces.
