| 英文摘要 | According to a program of Braverman, Kazhdan and Ng, for a large class of split unramified reductive groups G and representations rho of the dual group Ae, the unramified local L-factor L(s, pi, rho) can be expressed as the trace of pi(f (rho,s) ) for a function f (rho,s) with non-compact support whenever Re(s) ae << 0. Such a function should have useful interpretations in terms of geometry or combinatorics, and it can be plugged into the trace formula to study certain sums of automorphic L-functions. It also fits into the conjectural framework of Schwartz spaces for reductive monoids due to Sakellaridis, who coined the term basic functions; this is supposed to lead to a generalized Tamagawa-Godement-Jacquet theory for (G, rho). In this paper, we derive some basic properties for the basic functions f (rho,s) and interpret them via invariant theory. In particular, their coefficients are interpreted as certain generalized Kostka-Foulkes polynomials defined by Panyushev. These coefficients can be encoded into a rational generating function. |
