DESCRIPTION:Brown dwarfs and very low mass objects are found in large numb
 ers in star forming regions. They are usually associated with circumstella
 r accretion disks\, which appear to be scaled-down versions of the disks a
 ssociated with stellar mass objects. However\, the idea that the same form
 ation mechanism (i.e.\, core gravitational collapse) applies to all object
 s down to a few Jupiter mass is dubious\, and a number of alternative poss
 ibilities have been put forward over the years. Similarly\, the  evolution
  of brown dwarf disks to form planetesimal and planets poses a number of c
 hallenges to our theoretical understanding of these processes.\n\nIn this 
 talk\, I will review new Herschel and Alma observations and their implicat
 ions for both the brown dwarf formation mechanism and the subsequent disk 
 evolution.
