AbstractIn the present work, we establish the approximation via modulation or amplitude equations of nonlinear stochastic partial differential equation (SPDE) driven by cylindrical α-stable Lévy processes. We study SPDEs with a cubic nonlinearity, where the deterministic equation is close to a change of stability of the trivial solution. The natural separation of time scales close to this bifu...
AbstractThis will be a week-long workshop held at Tsinghua Sanya International Mathematics Forum (TSIMF), from January 2nd to 8th, 2023. The workshop will be held in a hybrid mode. Most talks will be held offline, but the participants can attend the talks on Tencent meeting.In the last two decades, there have been great progresses in probability and stochastic analysis. In particular, four Fiel...
