Abstract

A program for numerical computations of the photometric and chemical evolution of galaxies is developed. Some initial results are presented suggesting future applications of the program. Each run of model computation has been performed in time steps of 107yr with only the three fundamental parameters of the chemical evolution, i.e., the coefficient ν of star formation rate, the power index μ of initial stellar mass function, and the age TG of the galaxy.
