SUMMARY:Alexander Bufetov (I2M\, CNRS\, Marseille): Infinite determinantal 
 measures and the ergodic decomposition of infinite Pickrell measures
DESCRIPTION:Alexander Bufetov: The main result of the talk gives an explici
 t description of the ergodic decomposition for infinite Pickrell measures 
 on spaces of infinite complex matrices. The main construction is that of s
 igma-finite analogues of determinantal measures on spaces of configuration
 s. An example is the infinite Bessel point process\, the scaling limit of 
 sigma-finite analogues of Jacobi orthogonal polynomial ensembles. The stat
 ement is that the infinite Bessel point process (subject to an appropriate
  change of variables) is precisely the ergodic decomposition measure for i
 nfinite Pickrell measures.\nhttps://hal.archives-ouvertes.fr/EC-MARSEILLE/
