Abstract
Instead of assuming that they depend only on the background variables, we investigate the hypothesis that counterterms appearing in the deformed algebra approach to loop quantum cosmology depend on the full phase-space variables. We derive the associated anomalies and solve the entire system in several specific cases. New restrictions on the generalized holonomy corrections are obtained.
