Influence from cosmological uncertainties on galaxy number count at
  faint limit
  Counting galaxy number density with wide range sky surveys has been well
adopted in researches focusing on revealing evolution pattern of different
types of galaxies. As understood intuitively the astrophysics environment
physics is intimated affected by cosmology priors with theoretical estimation
or vise versa, or simply stating that the astrophysics effect couples the
corresponding cosmology observations
  or the way backwards. In this article we try to quantify the influence on
galaxy number density prediction at faint luminosity limit from the
uncertainties in cosmology, and how much the uncertainties blur the detection
of galaxy evolution, with the hope that this trying may indeed help for precise
and physical cosmology study in near future or vise versa
