Query: Uniqueness of Measures in Loop Quantum Cosmology   In a paper of Ashtekar and Campiglia, residual diffeomorphisms have been used
to single out the standard representation of the reduced holonomy-flux algebra
in homogeneous loop quantum cosmology (LQC). We show that, in the homogeneous
isotropic case, unitarity of the translations w.r.t. the extended
$\mathbb{R}$-action (exponentiated reduced fluxes in the standard approach)
singles out the Bohr measure on both the standard quantum configuration space
$\mathbb{R}_\mathrm{Bohr}$ as well as on the Fleischhack one. Thus, in both
situation, the same condition singles out the standard kinematical Hilbert
space of LQC.
