Query: Gamma Ray Burst Constraints on Ultraviolet Lorentz Invariance Violation   We present a unified general formalism for ultraviolet Lorentz invariance
violation (LV) testing through electromagnetic wave propagation, based on both
dispersion and rotation measure data. This allows for a direct comparison of
the efficacy of different data to constrain LV. As an example we study the
signature of LV on the rotation of the polarization plane of $\gamma$-rays from
gamma ray bursts in a LV model. Here $\gamma$-ray polarization data can provide
a strong constraint on LV, 13 orders of magnitude more restrictive than a
potential constraint from the rotation of the cosmic microwave background
polarization proposed by Gamboa, L\'{o}pez-Sarri\'{o}n, and Polychronakos
(2006).
