Models of Late-Type Disk Galaxies: 1-D Versus 2-D
  We investigate the effects of stochasticity on the observed galaxy parameters
by comparing our stochastic star formation two-dimensional (2-D) galaxy
evolution models with the commonly used one-dimensional (1-D) models with
smooth star formation. The 2-D stochastic models predict high variability of
the star formation rate and the surface photometric parameters across the
galactic disks and in time.
