DESCRIPTION:Speaker: Antoine Jego\nhosted by M. Beiglboeck\, N. Berestycki\
 , L. Erdoes\, J. Maas\nAbstract: The study of thick points of planar rando
 m walk\, that is points where the walk goes back unusually often\, goes ba
 ck to a famous paper of Erdos and Taylor in 1960. This talk will be dedica
 ted to recent progress on this topic. I will in particular discuss the sca
 ling limit of the set of thick points\, considerably refining estimates of
  Dembo\, Peres\, Rosen and Zeitouni. This scaling limit is described by a 
 random measure which is the analogue of Gaussian multiplicative chaos meas
 ures for the local times of planar Brownian motion. I will discuss the con
 struction of this new object and some of its properties. Finally\, I will 
 explain a characterisation of this random measure which is a key step in t
 he proof of the above scaling limit.
