Geometry & Topology Seminar

Place: This is an online seminar. We use University of Haifa moodle , please e-mail David Blanc <blanc@math.haifa.ac.il> if you would like to join.
Time: 10:00

Abstract:
It is a famous result of Harish-Chandra that every non-compact Hermitian symmetricspace can be realized as a bounded domain in a complex vector spaces. If we replace thecomplex numbers C by the division algebra of quaternions H in the definition of Hermitiansymmetric spaces, we obtain the class of quaternion-Kähler symmetric spaces. While thesespaces emerge in an analogous way, we show that there is no quaternionic analogue ofHarish-Chandra’s embedding theorem: A quaternion-Kähler symmetric space is integrableif and only if it is of rank 1. In the talk I will explain some of the background and some ofthe tools used in the proof.
