Speaker: Haotian Wu, The University of Sydney Title: Ricci solitons and their stability under Ricci flow Abstract: Abstract: Ricci solitons are fixed points of the Ricci flow dynamical system on the space of Riemannian metrics. In this talk, we look at the stability of some Ricci solitons. For example, the standard round sphere is stable under Ricci flow, whereas the Fubini-Study metric on complex projective space is not. In particular, we explore the asymptotic behaviour of unstable perturbations of Fubini-Study metric in Ricci flow.
