Structure of quantum cohomology

Zero section description

Fano 3-folds from homogeneous vector bundles over Grassmannians gives the following description(s):

- variety
- $\mathbb{P}^2 \times \mathbb{P}^4$
- bundle
- $\mathcal{O}(0,2) \oplus \mathcal{Q}_{\mathbb{P}^2}(0,1)$

See the big table for more information.

K-stability

- none are K-stable
- every member is K‑polystable
- every member is K‑semistable
