Query: An Empirically Based Model for Predicting Infrared Luminosity Functions,
  Deep Infrared Galaxy Counts and the Diffuse Infrared Background   We predict luminosity functions and number counts for extragalactic infrared
sources at various wavelengths using the framework of our empirically based
model. Comparisons of our galaxy count results with existing data indicate that
either galaxy luminosity evolution is not much stronger than Q=3.1, where L is
proportional to (1+z)^{Q}, or that this evolution does not continue beyond a
redshift of 2. However, a derivation of the far infrared background from
COBE-DIRBE data suggests a stronger evolution for far infrared emission with Q
> 4 in the redshift range beteen 0 and 1. We discuss several interpretations of
these results and also discuss how future observations can reconcile this
apparent conflict. We also make predictions of the redshift distributions of
extragalactic infrared sources at selected flux levels which can be tested by
planned detectors. Finally, we predict the fluxes at which various future
surveys will become confusion limited.
