DESCRIPTION:Speakers: Alexey Toporensky (Sternberg Astronomical Institute)
 \nWe consider Bianchi IX dynamics of a Universe filled with a massless pha
 ntom field. Such an exotic matter source enables regimes impossible in vac
 uum or with a standard scalar field. In particular\, two Kasner indices of
  BKL oscillations can be simultaneously negative\, and the absolute value 
 of a negative index can be large. We describe the consequences of these fe
 atures and explain the nature of volume oscillations recently discovered  
 in such a system by numerical methods.\n\nhttps://indico.itp.ac.cn/event/4
