Representation Theory 2016-04-12 v2 Differential Geometry

Abstract

Harish-Chandra's volume formula shows that the volume of a flag manifold G/TG/T, where the measure is induced by an invariant inner product on the Lie algebra of GG, is determined up to a scalar by the algebraic properties of GG. This article explains how to deduce Harish-Chandra's formula from Weyl's law by utilizing the Euler-Maclaurin formula. This approach leads to a mystery that lies under the Atiyah-Singer index theorem.
