/ Abstract
We study the luminosity function and the correlation function of about 1200 z~4 Lyman break galaxies (LBGs) with i' 3 sigma significance level. Interpreting this as being due to galaxy mergers, we evaluate the fraction of galaxies undergoing mergers to be 3.0 +/- 0.9%, which is significantly smaller than those of galaxies at intermediate redshifts.
