Title:  H-type fibration of spheres over symmetric spaces and its sub-Riemannian geometry.


Speaker: Professor Genkai Zhang (Chalmers Univ. of Tech. and Gothenburg Univ., Sweden)


Abstract: The circle bundle of a line bundle over a Hermitian symmetric space and the 3-sphere bundle 

               over quaternionic symmetric spaces have a sub-Riemannian structure and the corresponding 

               curvature satisfies certain quadratic condition. We introduce a class of H-type fibrations over 

               symmetric spaces generalizing these sphere bundles and study their sub-Riemannian geometry 

               including heat kernel, Weyl type estimates for the eigenvalue of the sub-Laplacian.


Time: 10:00-10:50 am, April 21  (Saturday), 2018 


Place:  Room 200-9 of the Sir Run-Run Shaw business building, Yuquan campus
