Jin Li (Freiburg) will speak in the geometry seminar at 2pm on 23rd June, in the Salle des Profs (9th floor, building NO). Jin’s title is “On the geometry of resolutions of G2-conifolds” and his abstract is below.
Given a compact G_2 manifold with isolated conical singularities, the process of resolutions of these singularities gives us a one-parameter family of G_2 structures, which can be viewed as a curve in some moduli space. This talk reports the progress in estimating the length of the curve under some Riemannian metric on the moduli space.
