The Stochastic Processes, Analysis and Semigroups Summer School will take place August 30 to September 3 2021 at the University of Trento (Italy). It is a one-week summer school for Master and PhD students and is co-organized by the Universities of Trento and Wuppertal. It will consist of four minicourses, delivered in a hybrid in-person/online mode:     Introduction to the Large Deviations Theory (Mariem Abdellatif, Wuppertal)     Asymptotics and ergodic properties of operator semigroups (Bálint Farkas, Wuppertal)     SPDEs with multiple limiting distributions (Martin Friesen, Dublin City and Barbara Rüdiger, Wuppertal)     Singular stochastic PDEs and renormalization of Anderson Hamiltonian (Baris Ugurcan, Wuppertal). The school is made possible by funding of the University of Trento, within the Department of Excellence project. There are limited resources available to partially cover local expenses of some of the participating students.
