Abstract
It is commonly believed that cosmological objects such as galaxies were formed through gravitational instability of initially small density fluctuations. One of the great successes of the inflationary universe scenario is that it has a possibility to explain the origin of these initial fluctuations naturally by quantum fluctuations of the scalar field which drives inflation.
