DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GeoSem/17/">
 On the signature of the Ricci curvature on nilmanifolds</a>\nby Ramiro Laf
 uente (The University of Queensland) as part of Geometry Seminar - Univers
 ity of Florence\n\n\nAbstract\nIn this talk we will explain the solution t
 o the following problem: Given an arbitrary nilpotent  Lie group\, determi
 ne all possible signatures of the Ricci curvature of left invariant metric
 s on it. The solution involves constructing invariant metrics with many ze
 ros in their Ricci curvature\, for which we use ideas from GIT\, and then 
 an Implicit function theorem argument.\n
