DESCRIPTION:Title: <a href="https://researchseminars.org/talk/VSGS/58/">O(
 2)-symmetry of 3D steady gradient Ricci solitons</a>\nby Yi Lai (Stanford 
 University) as part of Virtual seminar on geometry with symmetries\n\n\nAb
 stract\nFor any 3D steady gradient Ricci soliton with positive curvature\,
  we prove that it must be isometric to the Bryant soliton if it is asympto
 tic to a ray. Otherwise\, it is asymptotic to a sector and hence a flying 
 wing. We show that all 3D flying wings are O(2)-symmetric. Therefore\, all
  3D steady gradient Ricci solitons are O(2)-symmetric.\n
