Abstract

In this paper, a Chaudouard type trace formula is established for the Lie algebra gl(n)\mathfrak{gl}(n), by integrating the Lie algebra analogue of the Selberg kernel function against a mirabolic Eisenstein series on GL(n)\mathrm{GL}(n). The result is a combination of zeta functions ζE(s)\zeta_E(s) of extensions over the base field FF of degree [E:F]n[E:F]\leq n.

Comments

The author would like to express his gratitude to an anonymous referee who pointed out that in Definition 4.1 where the regularized mirabolic integral is defined, the summation over all parabolic subgroups is divergent. The author is currently working on the issue. Meanwhile, the author welcomes any ideas and suggestions on possible improvements via email
