Title: Fragmentation of circumstellar disks and its implications for star
and planet formation

The presentation is focused on the early stages of star formation when
circumstellar disks are often prone to gravitational instability and
fragmentation. I will demonstrate how disk fragmentation can trigger
episodic accretion onto the star, produce gas giants and brown dwarfs
on wide orbits and eject proto-brown dwarfs into the intracluster medium.
Finally, I will discuss the importance of external environment for the
early evolution of circumstellar disks.
