DESCRIPTION:Title: <a href="https://researchseminars.org/talk/VSGS/28/">Co
 homogeneity one quaternionic Kähler manifolds</a>\nby Daniël Thung (Univ
 ersität Hamburg) as part of Virtual seminar on geometry with symmetries\n
 \n\nAbstract\nThe study of quaternionic Kähler geometry has long been ham
 pered by a lack of examples. However\, a construction known as the c-map h
 as recently made it possible to construct many complete examples of negati
 ve scalar curvature. Moreover\, the quaternionic Kähler manifolds that ar
 ise from the c-map admit a one-parameter deformation through complete quat
 ernionic Kähler manifolds. In this talk\, I will describe the (deformed) 
 c-map in detail and show how to use it to construct interesting cohomogene
 ity one quaternionic Kähler manifolds\, focusing on a series of examples 
 which arise as deformations of quaternionic Kähler symmetric spaces. This
  is joint work with Vicente Cortés\, Markus Röser\, and Arpan Saha.\n
