Abstract:Recent observations have emphasized the importance of the
formation and evolution of magnetized filamentary molecular clouds in
the process of star formation. Theoretical and observational
investigations have provided convincing evidence for the formation of
molecular cloud cores by the gravitational fragmentation of
filamentary molecular clouds. Thus, the mass function and rotations of
molecular cloud cores should be directly related to the properties of
the filamentary molecular cloud, which determines the initial size and
mass distribution of a protoplanetary disk around a protostar created
in a core. In this talk I explain our current understanding of the
star formation processes in the Galactic disk, and summarize various
processes that are required in describing the filamentary molecular
clouds to understand the star formation rate/efficiency, the stellar
initial mass function, and the angular momentum distribution of
protoplanetary disks in their early evolutionary phase.
