Query: The Evolution of the Luminosity Function in Deep Fields: A Comparison
  with CDM Models   The galaxy Luminosity Function (LF) has been estimated in the rest frame B
luminosity at 0<z<1.25 and at 1700 {\AA} for 2.5<z<4.5 from deep multicolor
surveys in the HDF-N, HDF-S, NTT-DF. The results have been compared with a
recent version of galaxy formation models in the framework of hierarchical
clustering in a flat Cold Dark Matter Universe with cosmological constant. The
results show a general agreement for z<= 1, although the model LF has a steeper
average slope at the faint end; at z~3 such feature results in an
overprediction of the number of faint (I_{AB}~ 27) galaxies, while the
agreement at the bright end becomes critically sensitive to the details of dust
absorption at such redshifts. The discrepancies at the faint end show that a
refined treatement of the physical processes involving smaller galaxies is to
be pursued in the models, in terms of aggregation processes and/or stellar
feedback heavily affecting the luminosity of the low luminosity objects. The
implications of our results on the evolution of the cosmological star formation
rate are discussed.
