Abstract:
We find a full strongly exceptional collection for the Cayley plane $\mathbb {O}\mathbb {P}^2$, the simplest rational homogeneous space of the exceptional group $E_6$. This collection, closely related to the one given by the second author in 2011, consists of $27$ vector bundles which are homogeneous for the group $E_6$, and is a minimal Lefschetz collection with respect to the minimal equivariant embedding of $\mathbb {O}\mathbb {P}^2$.References
