Poles of unramified degenerate Eisenstein series
arXiv:2401.13093
Abstract
We determine the poles of maximal unramified degenerate Eisenstein series of a split semisimple algebraic group over a number field using a straightforward global argument, avoiding delicate analysis of intertwining operators.
Some minor computational errors are fixed. Restricted to the maximal parabolic case for clarity. Comments and corrections are gratefully received at [email protected]
