Abstract
We propose an expression for the star formation rate in spiral galaxies and a model of chemical evolution with a minimal number of adjustable paramete rs. Our model accounts for most of the relevant data in the Milky Way. By a dopting our Galaxy as a prototype, we are able to derive cosmological impli cations for the comoving star formation rate, gas amount, gaseous abundance s, and supernova rates as a function of redshift.
