Dear Colleagues,
We would like to invite you to the following Probability seminar that will take place on May 7 at 14.30 by the zoom platform. ________________________________________________________
Speaker: Gioia Carinci (Università di Modena e Reggio Emilia) Title: Condensation of SIP particles and sticky Brownian motion
7 MAY (Friday) - 14:30 zoom link: TBA available on the webpage https://www.math.unipd.it/~bianchi/seminari/ )
Abstract: The symmetric inclusion process (SIP) is a particle system with attractive interaction. We study its behavior in the condensation regime attained for large values of the attraction intensity. Using Mosco convergence of Dirichlet forms, we prove convergence to sticky Brownian motion for the distance of two SIP particles. We use this result to obtain, via duality, an explicit scaling for the variance of the density field in this regime, for the SIP initially started from a homogeneous product measure. This provides relevant new information on the coarsening dynamics of condensing particle systems on the infinite lattice. Joint works with M. Ayala, C Giardina and F. Redig
