Cayley 4-frames and a quaternion-Kähler reduction related to Spin(7)
Liviu Ornea, Paolo Piccinni
We describe an action of on that allows to obtain a -quotient of CAYLEY (the Grassmannian of oriented 4-planes in closed under the three-fold c…

Weyl structures on quaternionic manifolds. A state of the art
Liviu Ornea
This is a survey on quaternion Hermitian Weyl (locally conformally quaternion Kähler) and hyperhermitian Weyl (locally conformally hyperkähler) manifolds. These geometries appear b…

Geometric flow on compact locally conformally Kahler manifolds
Y. Kamishima, L. Ornea
We study two kinds of transformation groups of a compact locally conformally Kahler (l.c.K.) manifold. First we study compact l.c.K. manifolds with parallel Lee form by means of th…
