Abstract Let G be a rank 2 Kac-Moody group over a finite field. The group G comes equipped with a data (X, K), where X is the Tits building of G and K is the standard parabolic subgroup of the negative BN-pair. By using this data and the Iwasawa decomposition of G, we define Eisenstein series on the quotient graph KX, which is induced by a character defined on the set of vertices of X.
In this seminar, I will discuss this Eisenstein series, its convergence and meromorphic continuation.
This is a joint work with Lisa Carbone (Rutgers), Kyu-Hawn Lee (UConn) and Dongwen Liu (Zhejiang) (With an appendix by Paul Garrett (UMN)).
