Scientific paper
The paper considers many mechanisms, proposed for driving star formation: cloud collisions, induced star formation, gravitational instabilities, and spiral density waves. The consequences of their contemporary roles on the evolution of spiral galaxies are studied in the framework of the nonlinear multiphase model. A few relevant observational properties of the Hubble classification scheme are reproduced. A few cosmological aspects of the coupled halo and disk evolution are discussed.
