Abstrakt
Various isomorphisms theorem relate Gaussian free fields to random walk models, through their local times. Among them, the second Ray-Knight theorem can be extended in an isomorphism between the Gaussian free field and random interlacements on transient graphs. Following the work of Lupu and Sznitman, we will explain how the cable system method let us make this isomorphism more explicit, and how it relates to a certain cluster capacity functional for the Gaussian free field. Finally, we will present applications to percolation for the Gaussian free field on the cable system. Joint work with Alexander Drewitz (Cologne) and Pierre-François Rodriguez (London)

Due to the COVID 19 pandemic, events are currently taking place under restricted circumstances. We offer the seminar online, besides the opportunity to attend it in person in rooms 405/406. As these rooms have a limited capacity of 12 persons, due to hygiene recommendations, we kindly ask those who want to participate in person to register (put your name in the list) in the following google document. If 12 have already registered, please follow the streamed talk. The organisers will send the zoom link shortly before the time of the talk. Please contact the organisers if you are not included in the email list and you want to follow the talk or be kept up to date with the seminar.
