Noise sensitivity and stability problem on groups

The general noise sensitivity and stability problem asks: Given a stochastic process X defined in terms of i.i.d. variables, does resampling a small fraction of these variables produce an almost independent copy of X ? or a highly correlated copy? In this talk, we discuss the following questions: Can random walk on a group be noise sensitive? Which groups admit a noise sensitive random walk? [Talk based in part on joint work with Timothée Bénard (Paris).]

Valuative stability of polarized varieties and applications
AbstractRecently, Dervan-Legendre considered the valuative criterion of polarized varieties. We will study the valuative stability and show that it is an open condition. We would like to study the valuative criterion for the Donaldson's J-equation. Motivated by the beta-invariant of Dervan-Legendre, we introduce a notion, the so-called valuative J-stability and prove that J-stability implies va...
