The next speaker in the geometry seminar is Jason Lotay (from University College London) who will speak about The Laplacian flow in G2 geometry. We will finally return to our supposedly regular time and place, Tuesday 29th September, 14h-15h in the Salle de Profs (9th floor, building NO). Jason’s abstract is below.
A key challenge in Riemannian geometry is to find Ricci-flat metrics on compact manifolds, which has led to fundamental breakthroughs, particularly using geometric analysis methods. All non-trivial examples of such metrics have special holonomy, and the only special holonomy metrics which can occur in odd dimensions must be in dimension 7 and have holonomy G2. I will describe recent progress on a proposed geometric flow method for finding metrics with holonomy G2, called the Laplacian flow. This is joint work with Yong Wei.
Hope to see you all there!
