Pseudo-conformal quaternionic CR structure on (4n+3)-dimensional manifolds
Dmitri Alekseevsky, Yoshinobu Kamishima
The purpose of this paper is to introduce a geometric structure called pseudo-conformal quaternionic CR structure on a (4n+3)-dimensional mamnifold and then exhibit a quaternionic…

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…

Transformations of compact locally conformally Kähler manifolds
Yoshinobu Kamishima, Liviu Ornea
We characterize compact locally conformally Kähler (l.c.K.) manifolds under the assumption of a purely conformal, holomorphic circle action. As an application, we determine the str…
