Scientific paper
The authors present a modified optical evolution function of QSOs which is adequate for high redshift, even for z = 3.3. The physics consideration is based on the luminosity evolution resulted from both the variances of the mass and the accretion rate of the central object and luminosity-dependent density evolution due to the birth of QSOs at high redshift. This evolution function is more convenient for describing the dynamical characters of QSO evolution, and it can be determined through comparison with the following three observed results: (1) Magnitude counts of QSOs up to m = 22m0. (2) Redshift-distribution of QSOs over the interval Δz = 0.1. (3) Magnitude counts of QSOs with z > 2.
