18 Nov 2007 | Abstract: | We consider Baxter Q-operators for various versions of quantum affine Toda
chain. The interpretation of eigenvalues of the Baxter operators as local
Archimedean L-functions proposed recently is generalized to affine Lie
algebras. We also propose a simple generalization of Baxter operators and local
L-functions compatible with this identification. This gives a connection of the
Baxter Q-operators for Toda chains with an Archimedean version of Polya-Hilbert
operator proposed by Berry-Kitting. We also elucidate the Dorey-Tateo spectral
interpretation of eigenvalues of Q-operators. Using explicit expressions for
eigenfunctions of affine/relativistic Toda chain we also provide an Archimedean
analog of Casselman-Shalika-Shintani formula for Whittaker function in terms of
characters. Various conjectural arithmetical interpretations of the presented
results are discussed. | Source: | arXiv, 0711.2812 | Services: | Forum | Review | PDF | Favorites |
