Almost complex structures on quaternion-Kaehler manifolds Paul Gauduchon Ècole Polytechnique
Аннотация: The aim of this lecture is to show that, apart from the complex Grassmannians $Gr_2(C^{n+2})$, the compact quaternionic quaternion-Kaehler manifolds of positive type admit no almost complex structure, even in the weak sense (joint work with Andrei Moroianu and Uwe Semmelmann).
