SUMMARY:Alexander Bufetov (I2M\, Aix-Marseille Université): Mesures condit
 ionnelles des processus déterminantaux
DESCRIPTION:Alexander Bufetov: Determinantal point processes arise in many 
 different problems:\nspanning trees and Gaussian zeros\, random matrices a
 nd representations of infinite-dimensional groups. How does the determinan
 tal property behave under conditioning?\nThe talk will first address this 
 question for specific examples such as the sine-process\, where one can ex
 plicitly write the analogue of the Gibbs condition in our situation.\nWe w
 ill then consider the general case\, where\, in joint work with Yanqi Qiu 
 and Alexander Shamov\, it is shown that the determinantal property is pres
 erved under conditioning and a proof is given of the Lyons-Peres conjectur
 e on completeness of random kernels.\nThe talk is based on the preprint ar
 Xiv:1605.01400\nas well as on the preprint arXiv:1612.06751 joint with Yan
 qi Qiu and Alexander Shamov.\n\n&nbsp\;
