WebRational, or arithmetic, nilpotent adjoint orbits of algebraic groups over a local field k arise in representation theory in several contexts. For example, the Harish-Chandra–Howe char-acter formula locally expresses a character of a representation as a linear combination of (Fourier transforms of) nilpotent orbital integrals.
