Observational constraints on dual intermediate inflation
  We explore the observational implications of models of intermediate inflation
driven by modified dispersion relations, specifically those representing the
phenomenon of dimensional reduction in the ultraviolet limit. These models are
distinct from the standard ones because they do not require violations of the
strong energy condition, and this is reflected in their structure formation
properties. We find that they can naturally accommodate deviations from exact
scale-invariance. They also make clear predictions for the running of the
spectral index and tensor modes, rendering the models straightforwardly
falsifiable. We discuss the observational prospects for these models and the
implications these may have for quantum gravity scenarios.
